Our body

Role in the
series Explains the work of blood and immunity. In the series, the Spleen shows how the body gets rid of old cells and maintains a supply of new ones. This is presented through understandable images: the "old red balls" leave, the "fresh" ones remain.
He talks about immunity and protection. When an infection enters the body, the Spleen explains how it activates immune cells and helps the body fight. Shows the "warehouse" and reserve. She says that she keeps a supply of blood and cells in case of injury or blood loss. In the cartoon, this is shown as a "secret compartment" that opens only in emergency situations.
It creates a calm, reliable background. Her quiet voice and measured actions balance out the more emotional scenes - when the Brain panics and the Heart beats faster, the Spleen calmly says: "Everything is under control. I have a reserve" Relationships with other characters
With the hematopoietic system and leukocytes - she has "working connections". It is like a "dispatcher": it receives cells, checks them, and sends them to where they are needed.
With the Liver - almost colleagues in blood purification. The liver neutralizes toxins, the spleen removes old cells. Sometimes they talk: "I'm cleaning up the unnecessary here", "And I'm neutralizing the poisons here" – and together they keep the balance. With the Heart – The Heart pumps blood, the Spleen "sorts" it. She sometimes gently reminds: "Don't drive too fast - I need time to check everything."
With the Doctor - respectful and calm. The doctor asks questions, Spleen answers without any fuss, but very accurately. If the Doctor asks for "short", she can say: "I can't be short. But I can show on the diagram."
With the rest of the organs, she is like a quiet assistant: she does not climb forward, but is always ready to back up. If someone is stressed, the Spleen quietly says, "I have a reserve. If necessary, I will give it."

Appearance
Violet-lilac "bean". It is similar in shape to a kidney, but a little more elongated and with soft rounded edges - this is how it is immediately distinguished from other organs.
One eye and half a mouth. Like some other organs, she has "half a face": one expressive eye and a corner of her mouth that can both frown and smile softly.
Slight translucency. In the animation, she has a slight glow effect from the inside, which emphasizes that she is working with blood and cells. Mini accessories. Sometimes tiny "cells" or containers flash next to it - this shows that it stores and sorts cells.
Calm palette. The color is not aggressive, but muted, "night" - as if she is always ready, but does not want to attract unnecessary attention. The character and behavior
of the Spleen is such a modest, but principled "keeper of order":

"I watch the purity of the blood." Her favorite phrase sounds quiet but firm: "Old red blood cells are out, new ones are in line. I have a strict record here!"
Attentive and meticulous. It is constantly "sorting out" the cells: it checks who is still strong, and who has already worked out theirs. If it sees something suspicious, it immediately reports to the immune system. He does not like panic, but does not tolerate chaos. If inflammation or infection begins in the body, the Spleen does not scream, but acts: "So, I activate the reserves of white blood cells. We are holding the line."
Caring for "her own". She is very careful with healthy cells and tries not to lose a single extra one: "They will still be useful to me!"
A little shy. He does not like to be the center of attention and prefers to work "behind the scenes". But if the Doctor asks her, he opens up and explains everything in great detail.

Inquisitive and a little carefree. He is not a villain or an Olympic athlete, but an ordinary person who tries, makes mistakes, is surprised and learns. This is its main strength: through it, the child learns that this happens to him, and this is normal.
Sensitive to his body. He doesn't ignore feelings: if something is unpleasant, you can see it in the visuals. But he is not an alarmist: rather, he is genuinely surprised: "Oh, why is my heart pounding so much?" He doesn't have long monologues, but his behavior is questions without words. He does, and the organs and the Doctor immediately explain: "And now this is happening..."

Appearance
An ordinary guy in whom it is easy to recognize yourself. In the cartoon, it is drawn as simply and friendly as possible: no frightening anatomical details from the outside, only a clear silhouette.
Casual clothes. Most often, he is in a simple T-shirt and shorts or jeans - in the style of "I just live my normal life." The colors are calm, they do not distract from the main thing - what is happening inside. It changes to the situation. In different episodes, he has themed costumes: pajamas (for episodes about sleep), sports uniform (for sports), warm jacket (for cold). This immediately makes it clear what the episode is about.
A minimum of facial details. The face is not drawn in detail: it has simple features, the emphasis is not on the emotions outside, but on what is happening inside the body.
Emphasis on sensations. Instead of facial expressions on the outside, there are visual cues: if he is cold, light clouds of steam and goosebumps are drawn around him; if it is hot, drops of sweat; If he is frightened, there is like "electricity" and a harsh light around. This is how the viewer understands his state without words. Character and behavior
A person is the embodiment of an ordinary, lively, a little impulsive, but very curious you and me:

"I just wanted to try..." His actions are typical everyday situations, because of which all adventures inside the body begin: "ate spicy pizza", "ran to the bus", "forgot to put on a hat", "drank soda on an empty stomach". It is these simple actions that trigger a chain of explanations from the authorities.

Patient with arguments. When the organs quarrel, he does not shout, but pauses and says: "Stop. Let's listen to the Lungs first, then the Liver. And without interruptions." Role in the
series Guide and Moderator. The doctor appears in almost every episode and asks the topic: "What happens if you eat very spicy food?", "Why do we yawn?", "How does the body react to cold?". He starts a chain of explanations and makes sure that all the authorities participate.
It connects science and emotions. He doesn't just give facts, but shows how they feel: "Yes, it's okay to have a faster pulse, but you feel it like a heart in your throat." He creates comedic situations. His "harsh measures" (turn off the sound, remove the mouth) are one of the main sources of humor. At the same time, these scenes always end with a useful conclusion.
Sums up. At the end of the episode, the Doctor briefly formulates the main thing: "So, after a spicy meal: the brain registers irritation, the stomach turns on an enhanced mode, the liver prepares for the load, and the lungs remind that you need to breathe calmly." Relationship with the Brain Organs
is a partnership with easy competition. The brain wants to explain everything "according to science", the Doctor asks: "In short, in two sentences." They complement each other: the brain is the details, the doctor is the structure.
With the Heart – mutual respect. The heart gives dynamics, the Doctor "frames" it into understandable conclusions: "A rapid pulse is a reaction to load. Everything is under control." With the Stomach and Liver – the Doctor often "protects" them from a frivolous attitude to food. He might say, "Stomach, you don't have to handle pizza at 2 a.m. Let's discuss the alternatives."
With the Lights, there is a calm, respectful relationship. The lungs like to explain in a measured manner, the Doctor is not in a hurry: "Let me finish taking a breath, and I will write everything down."
With the Kidneys and Intestines – he appreciates their "routine" work and often emphasizes: "They don't scream, but they do the most important thing."

Appearance:
White cartoon hand. This is his main feature: not a person or a robot, but a hand with five fingers – it is immediately clear that he is "inside the process", literally touching the topic.
Minimalist style. No unnecessary details: a clean white uniform, clear contours so as not to distract from the organs.
Expressive gestures. Depending on the scene, he can be a relaxed palm, a strict index finger or even a clenched fist - this is how his mood is conveyed without words. Changing "regimes". In different episodes, he has funny variations: he is like a mouse cursor (in short sketches), then he appears with a sign, then he makes a gesture "stop" or "attention". This adds humor and emphasizes that he is the voice of the narrator.
There is no face, but there is character. The Doctor's emotions can be read in the posture, tilt of the fingers and dynamics: he can "freeze" with surprise, sharply point out the problem or calmly summarize. Character and behavior
The doctor is a balance between authority and self-irony:

"I'm here to ask the right questions." His task is not to know everything, but to help others figure it out. He often begins with: "What is happening now?" or "Explain to me in simple words."
Ruthless, but with a drop of kindness. He can turn off the sound to the Brain so that it does not talk too much, or "remove the mouth" of the Stomach if it is too dramatic. But he does it not out of malice, but to restore order: "So, let's get down to business!" If the organs are oversimplified, he gently but firmly returns to the point: "It's not just 'pumping blood', it's pressure, volume, resistance..." At the same time, he is not a bore: he immediately translates complex things into understandable language.
With a sense of humor. His jokes are more often ironic comments and precise formulations. For example: "Chips again? Well, let's see how the Liver copes with it" or "Heart, don't drive it like that — I still have to explain why the pulse is 140."

Relationships with other characters
With Stomach are a real working couple. The stomach "softens" the food, and the intestines "bring it to mind". Sometimes the Stomach grumbles that the Intestines get the most boring part of the work, and the Intestines calmly replies, "But I take all the most valuable things!"
With the Liver, they have a "chemical partnership". The liver helps with the processing of fats and toxins, the intestines take away nutrients. They often talk about balance and how best to allocate resources. With the Brain – the Brain likes to explain processes "according to science", and the Intestines translate it into understandable language: "In short, I suck here, and the Brain tells me what it's called."
With the Doctor - respectful and calm. The Doctor asks questions, the Bowel answers in detail, sometimes even too detailed, and the Doctor gently stops him: "That's enough, I understand!"

Patient, but with boundaries. If a Person eats something completely inappropriate (too spicy, too cold, too large), the Intestines do not throw a tantrum, but gently but firmly remark: "It's not easy for me here. Let's be a little calmer next time?"
Caring for balance. He is very worried about the microflora and tries to explain that beneficial bacteria are his "helpers", and they must be protected. Role in the
series Explains absorption and assimilation. In the series, The Gut shows how nutrients "seep" through the walls into the blood so that the body receives energy, proteins, vitamins. This is presented through understandable images: small luminous "utilities" go into the vessels, and the rest moves on.
He talks about the microflora. In the episodes about yogurt, kefir or fiber, Gut explains how beneficial bacteria help digest food and protect the body. It shows peristalsis. In scenes where Man moves, runs, or even dances, the Intestines demonstrate how movement helps digestion: "When you walk, it's easier for me to work!"
Creates a calm contrast. His measured lines and fluid movements balance out the noisier characters like the Brain or the Kidneys.

Appearance:
A long, winding ribbon. The intestine is shown as a long, gently curved tube with smooth loops - it is immediately clear that it needs a lot of space. The animation makes it "cozy" on purpose, not frightening: no hard details, just smooth lines.
Two in one. In the cartoon, it is clearly seen that this is a duet: the small intestine (it is engaged in "suction") and the large intestine (it collects and excretes the remains). A thin one is a little lighter and thinner, a thick one is darker and wider. Warm beige-pink color. Not bright red, but such a calm, "working" shade - it immediately sets you up for a measured mood.
Soft texture. The surface is not smooth, but as if slightly velvety, with delicate folds - so they emphasize that delicate work is going on inside.
Expressive curves. In the animation, the loops of the Intestines move gently – this shows peristalsis (wave-like contractions) that push food forward. Facial expressions of a "calm workaholic". The Intestine's face is not flashy, but collected: he seems to be concentrating all the time: "Okay, now the main thing is not to rush and do everything right." Character and behavior
The intestines are the embodiment of patience and consistency:

"I'm carefully sorting everything out here." He says quietly but confidently: "Don't be in a hurry. First I will take everything useful, and then the rest will go further."
Calm and reasonable. Even when other organs panic or argue, the gut remains unfazed: "Give me time. I have a trial here."
A little philosophical. Sometimes he thinks aloud about how important it is not to rush digestion: "If you are in a hurry, nothing will be absorbed. Everything must take its course."

Role in the
series Blood Filtration Explained. In the episodes, Kidneys shows how excess salts, toxins and metabolic products are removed from the blood. This is presented through understandable images: "dirty" balls go into the "waste", and pure blood flows further.
They talk about urine and fluid balance. They explain why we go to the toilet, how the kidneys decide how much water to leave in the body and how much to excrete. They react to the load. In episodes about sports, heat or dehydration, the kidneys clearly show how their work changes: in the heat, they try to conserve water, in excess of fluid, they speed up filtration.
They create a comedic effect. Their synchronized lines, squeaky tone and panic because of the "extra salt" perfectly dilute even the most scientific scenes. Relationships with other characters
S Pechen are almost colleagues in the "cleansing". The liver neutralizes toxins, the kidneys remove them. Sometimes they argue about who is more important: the Liver says: "I do the most difficult thing!", and the Kidneys in unison: "And we remove everything – there is no way without us!", but in fact, they complement each other perfectly.
With the Heart – working partners. The heart pumps blood, the kidneys filter it. The kidneys often remind: "Don't drive too fast, I need time to clear everything!" and the Heart cheers up: "Keep the rhythm, I'll adjust!" The brain may say, "Osmoregulation and glomerular filtration...", and the Kidneys interrupt: "In short, we decide how much water to keep and how much to remove!"
With the Doctor - respectfully, but with a slight panic. When the Doctor asks difficult questions, the Kidneys sometimes start talking even faster and louder, as if they want to prove that everything is under control.

Appearance:
Two identical beans. The buds are drawn as classic cartoon "beans" in dark burgundy with a slight gradient to look voluminous, but not frightening.
Each has one eye and half a mouth. A funny detail: each kidney has one eye and a "half" of a mouth. When they talk together, it looks like a synchronized duet – very comical.
Vessels are like tubes. Vessels come and go to them, in the cartoon they look like flexible hoses: according to some, "dirty" blood comes, according to others, already purified blood leaves. Slight pulsation. In animation, they are rhythmically slightly compressed and unclenched, which emphasizes that filtering is continuous.
Sparks or transparent droplets. Sometimes small sparks (a sign of active work) or transparent droplets are drawn around them - a symbol that they are "selecting" excess liquid and waste. Personality and behavior
Kidneys are energetic perfectionists who can't stand "garbage" in the body:

"We filter everything here!" We cleanse the blood of toxins and turn waste into urine!" - and they pronounce it sonorously, almost in unison.
Fussy, but reliable. They are constantly "checking" the flows, making sure that nothing superfluous remains in the blood. If something goes wrong, they begin to worry: "Oh, there's too much salt here!" or "We need to urgently remove excess water!" Their voice is high and fast - this adds dynamics and comedy: it seems that they are always in a hurry and control everything.
Fair and strict to harmful substances. If a Person eats something too salty or drinks soda, the Kidneys immediately react: "Well, we have to work overtime again!"
Caring for balance. They are very worried about the water-salt balance: "You can't drink too much – otherwise we won't be able to cope!", "And you can't drink too little – then we have nothing to filter!"

Role in the
series Explains detox and metabolism. In the series, the Liver shows how the body deals with toxins, why it's important not to overload it, and how it helps regulate sugar and fat levels.
He talks about bile and digestion. She explains why bile is needed, how it helps digest fats and what happens if this process is disrupted.
Raises important topics. In the episodes about food, alcohol, and medications, the Liver becomes the main expert: it speaks honestly about the risks, but without intimidation — through understandable images and examples. Creates balance in the team. When the Brain is over-theorizing and the Stomach is panicking, the Liver brings everyone back to the facts: "Let's get down to business. That's what's really happening." Relationships with other characters
of S Zheludok - they have "working friction". The stomach sometimes grumbles: "You always complicate everything!", and the Liver replies: "And you always simplify everything!"
With the Brain - almost colleagues. The brain gives the big picture, the liver gives the details and chemistry. Sometimes they argue about terms, but they respect each other. With the Heart – calm, business-like relations. The heart pumps blood, the liver "cleanses and cooks" it. They often work synchronously, and the Liver appreciates that the Heart does not rush its processes.
With the Doctor, they are respectful, but with a slight wariness. The liver likes it when the Doctor asks clear questions, but it doesn't like it when he simplifies complex things. Her reaction: "It's not as easy as it seems!"

Appearance
The cartoon shape of the liver is a recognizable dark red-brown silhouette with smooth curves, without frightening anatomical accuracy, but it is immediately clear that this is her.
Gallbladder as an accessory. In the cartoon, he is shown as a small pouch next to the Liver - he seems to be her "assistant" or even a "microphone", through which she sometimes protests especially loudly.
Expressive "creases" and texture. The surface is not smooth, but with a light porous structure - so they emphasize that complex processes are constantly going on inside. The color is warm, but serious. Not bright red, like the heart, but such a "working" brown-burgundy - immediately sets you up for a business mood.
Facial expressions of a "strict teacher". The liver has very expressive eyebrows (yes, the cartoon organ has them!), she knows how to frown, roll her eyes and make a face as if she is saying: "Well, as much as possible!"

if a Person does something harmful. Her catchphrase could be: "I'm not a filter for everything!"
Strict, but caring. She grumbles when something dubious gets into her body, but she does it not out of anger, but because she is worried: "I will have to neutralize it all later!" He likes to explain processes in detail, sometimes even too much. Other organs sometimes ask her: "In short, Liver, in a nutshell!"
Patient, but with a limit. She is ready to cope with the loads, but if it's too much, she can give a whole lecture about the consequences.
With a sense of humor, but dry. Her jokes are more often ironic comments: "Oh, chips again. My Favorite Tuesday".

Role in the series
Explain gas exchange in simple words. In the episodes, the lungs show how oxygen "enters" the blood, and carbon dioxide "escapes" to the outside. This is presented through images: oxygen is like small glowing balls, and CO₂ is like gray clouds that need to be released.
They react to different conditions. In the episodes about sports, altitude or cold, the lungs clearly show how breathing changes: when running, the breaths become shorter and more frequent, in the mountains - deeper, and in the cold - a little more careful Relationships with other characters
With a Heart is a real working team. The lungs say: "I give oxygen", and the Heart answers: "And I carry it". They often joke about the "general plan" and try to synchronize their rhythms.
With the Brain, there are slightly different styles: the Brain likes complex terms, and the Lungs prefer simple analogies. Sometimes the Brain tries to explain something "scientifically", and the Lungs gently interrupt: "In short, I just need the air to be clean and warm." With the Doctor - respectful and calm. They willingly answer questions, but ask not to rush them: "Let me finish taking a breath and I'll tell you everything!"
With the Stomach – sometimes they make fun of each other: the Stomach grumbles that "food interferes with normal breathing", and the Lungs answer: "But you don't feel how you don't have enough air sometimes!" Their smooth movements and "whisper" ("Breathe in... Exhale...") set a calm tone for the scenes, contrasting with noisier organs like the Brain or the Stomach.

Appearance
Two characters at once - Right and Left lung. They are almost the same, but with a cute detail: the Left lung has a small dent on one side — because the Heart lives nearby, and it needs to move a little.
Fluffy, porous texture. In the cartoon, they are not smooth, but seem to consist of many tiny cells - so you can immediately see that "magic" with the air is happening inside.
Pale pink color. Not a bright, but a calm, "breathing" shade - it makes them less frightening for children. Expressive contours. They have soft lines that smoothly expand and contract in the animation — this is the inhalation and exhalation.
Facial expressions without sharp angles. The faces of the Lungs are very delicate: they do not scream or panic, but rather gently surprise, frown slightly or exhale with relief. Character and behavior
Lungs are such neat perfectionists who love order in the air:

"Hush, I count the breaths!" It adds to the comedy when someone (like the Brain) starts fussing.
Calm, but persistent. If something in the body prevents you from breathing (for example, dust or too tight clothes), the lungs do not make a scandal, but politely but firmly say: "I don't have enough volume here!" They don't like to be the center of attention and prefer to explain processes quietly so as not to interrupt others. But if the Doctor asks them a question, they open up and tell everything on the shelves.
Caring. Especially in relation to the Heart: after all, it is the Lungs that saturate the blood with oxygen so that the Heart can pump it. They often cheer him up: "Don't worry, I'll prepare everything!"

Relationships with other characters
With the Brain are slightly different languages: the Brain talks about "fermentation and pH", and the Stomach replies: "In short, it's an acidic environment, and I mix everything." But they respect each other: the brain explains science, the stomach explains sensations.
There is a good, warm relationship with the Heart. The heart cheers up: "Keep the rhythm, you can do it!", and the Stomach jokes in response: "The main thing is that the pulse does not interfere with my digestion!"
With the Doctor - respectfully, but sometimes with irony. When the Doctor asks difficult questions, the Stomach can answer: "I'm not a textbook, I'm a working organ! But in short, yes, there is acid, yes, I digest everything."

Appearance
Cartoon "comma". The shape is like that of an anatomical stomach, but stylized: smooth curves, a recognizable silhouette, without frightening details.
Warm pink-red color. Not bright scarlet, but so cozy, as if it is always "warm" - as if a process is going on inside it right now.
Expressive face. He has very lively facial expressions: he can wince at "tasteless" food, roll his eyes when he gets something heavy, or smile happily if the Human has eaten his favorite fruit salad. Slight "pulsations". In animation, it shrinks and unclenches a little rhythmically, which emphasizes that it is constantly working, stirring, and digesting.
Character and behavior
Zheludok is one of the most down-to-earth and at the same time very soulful characters:

"I digest everything here, and it's not easy!" He likes to joke about food: "Chips again? Well, okay, I can do it!" or "Fruit salad – that's what I understand!"
A little disturbing. If the Man eats something strange or too spicy, the Stomach begins to worry: "Oh, oh, there is going to be a storm here!" - and in the frame it is shown as a slight "seething".
Patient. Even when other organs grumble or argue, the Stomach tries to stay calm: "Give me half an hour, I'll put everything on the shelves... well, molecules." Role in the
series Explains digestion in simple words. In the series, he talks about how hydrochloric acid works, why enzymes are needed, why you can't swallow large chunks, and what happens to food next (goes to the Intestines).
Shows the connection between food and well-being. For example, in the episode about fast food, Stomach honestly says that it is hard for him, and explains why there is discomfort after such a meal.
Creates everyday and funny situations. He often becomes a "victim" of Human habits: he gets a pizza that is too hot, then a huge sandwich, and he heroically copes with it.

Appearance
Cartoon Heart is a recognizable classic shape, bright red, stylized, without unnecessary anatomical details, but very expressive.
Vessels are like "wires" — vessels depart from it, which in the frame look almost like cables or cords, emphasizing that it literally "nourishes" the entire body.
Live emotions – the Heart is great at conveying mood: it can "pulsate" with excitement, change color when worried, or literally glow with joy. Simple but charismatic animation - in motion, it seems to beat the rhythm, emphasizing its main function: to work non-stop. Personality and behavior
The heart is one of the most positive and energetic characters:

"DJ of the body". In the series, it likes to say things like, "I'm pumping blood all over my body so the party doesn't end!" and does so with genuine enthusiasm.
Friendly and peaceful. He does not like quarrels, tries to smooth out conflicts between other organs, and if someone argues (for example, the Brain and the Liver), the Heart tries to reconcile everyone. Role in the
series Explains Blood Circulation. In different episodes, the Heart tells how the blood carries oxygen and nutrients, why the pulse increases when running or fearing, and what happens when we freeze or overheat.
Reacts to emotions. It clearly shows how feelings affect the body: joy speeds up the rhythm, fear makes you beat faster, and fatigue makes you work a little quieter.
It creates dynamics and humor. His rhythmic lines, "pulsation" and attempts to keep the overall tempo add energy and comedic to the episode. Relationships with other characters
in The Doctor are strained, but interdependent. The Doctor asks questions and sets tasks, the Brain tries to look omniscient, but the Doctor regularly puts it in its place (including literally turning off his voice).
With the rest of the bodies - as a strict, but not always logical leader. The heart, stomach and others either obey him, or make fun of his ideas.

Appearance
A typical cartoon brain is a recognizable sinuous shape, everything is like in textbooks, only in a comedic presentation.
There is a lower process — it is like an extension of the brain stem, it adds "solidity" to the character and at the same time helps him move in the frame.
Small glasses are the main accessory. They immediately make him look like a scientist who knows everything (or thinks he does).
Expressive facial expressions - despite the strange shape, he is excellent at showing emotions: surprise, self-satisfaction, confusion. Personality and behavior
The brain is the main speaker and coordinator among the organs, but with a bunch of funny quirks:

Intelligent, but self-confident. He loves to explain how everything works, and often begins a phrase with words like: "I'm in charge here, I'm in control!"
Apathetic and sudden. Sometimes he sluggishly comments on what is happening, as if he does not care, then suddenly he lights up with some crazy idea and drags the whole team with him. A little "out of my mind". Other authorities often consider him crazy – and with good reason: he may start philosophizing at the most inopportune moment or come up with an absurd solution to a problem.
Touchy towards the Doctor. Especially when the Doctor "turns off the sound" or removes his mouth altogether – this is a real drama for the Brain, and he tries very hard to regain the right to vote. Role in the
series Explains the processes. In almost every episode, the Brain tells what happens in the body: why we feel pain, how memory works, what happens when we sleep or are frightened.
Coordinates the team. If something goes wrong in the body, it is the Brain that tries to bring everyone together and come up with a plan. However, not always successfully.
It creates a comedic effect. His contradictory reactions, mood swings and attempts to command the rest of the organs are one of the main sources of humor in the cartoon.

What organs are there and what is known
about them I have selected brief "portraits" of the main organ characters:

The brain is the control center. It sends signals through the nervous system to all parts of the body, coordinates the work of other organs.
The heart is a pump that pumps blood, delivering oxygen and nutrients.
The lungs are responsible for breathing: they absorb oxygen from the air and remove carbon dioxide.
The liver performs many important functions: cleanses the blood, participates in metabolism, and produces bile.
Kidneys – filter blood, remove harmful substances and excess fluid from the body.
The intestines continue the process of digestion, absorb useful substances.
The pancreas produces enzymes for digestion and hormones (such as insulin) that regulate blood sugar levels. The spleen is involved in immune defense and blood filtration. Characters in addition to the Doctor's organs
. This is a key character, he appears in almost every episode. It looks like a cartoon white five-fingered hand. His character is contradictory: ruthless, but with a drop of kindness. He acts as a guide: he asks questions, helps the authorities understand situations, and sometimes makes jokes. At the same time, it is important: the Doctor is not a know-it-all: he understands medicine, but not in all areas (for example, the authorities try not to discuss technologies that can replace doctors in the future). Daktor. Do not confuse with the Doctor! This is his cousin, who appeared in the episode "How is human anatomy different from apes?". It looks like a blue cartoon hand. By nature, he is a little insane. In the story, he is a veterinarian who invented a serum to broaden his horizons, and owns a clinic (possibly a veterinary).
A person is the owner of this "house".
The Human's Wife and the Man's Dog are secondary characters that add everyday situations to the plot
