Map of Human Body
Explore & simulate how the organ systems work. Pick an organ below to open an interactive analysis.
Brain Não bộ
A living neuron network, a 7-region EEG, an interactive 3D cortex and 8 neurological disease modes.
Neuron Nơ-ron & Synap
An action potential −70→+40 mV leaping node to node (Ranvier) to the synapse; threshold, refractory period & 6 disorders (demyelination, anesthesia, toxins…).
Eye Mắt
A 2D cross-section + 3D eyeball, accommodation optics, a ‘what you see’ simulation & 10 vision disorders.
Heart Tim
A cross-section of 4 pumping chambers, a live ECG, chamber pressures & rhythm states.
Lung Phổi
A living breathing chest, lungs inflating-deflating & the diaphragm, a volume spirogram and respiratory states.
Kidney Thận
A kidney cross-section + a living filtering nephron, filtrate → urine, GFR & 5 disorders.
Stomach Dạ dày
Living peristalsis churning food, HCl acid & digestion, 5 disorders (ulcer, reflux…).
Ear Tai
The vibrating ossicle chain, the coiled cochlea & a tonotopic frequency map; live sound waves. Deafness, tinnitus.
Pancreas Tuyến tụy
Islets of Langerhans secreting insulin/glucagon to regulate blood sugar (a live feedback loop). Type 1/2 diabetes.
Muscle Cơ
Muscle contraction at the sarcomere level (living actin–myosin), motor units & EMG. Cramps, atrophy, myasthenia.
Bone Xương & Khớp
A living flexing synovial joint, compact/spongy bone structure & the Haversian system. Osteoporosis, osteoarthritis, fractures.
Vessels Mạch máu
A pulsing artery + live pressure wave, red-cell flow, venous valves. Atherosclerosis, hypertension, aneurysm.
Skin Da
3 skin layers + follicles/glands/receptors, live thermoregulation (vasodilation-constriction, sweat, goosebumps). Burns, eczema, acne, melanoma.
Liver Gan
Hexagonal lobules filtering portal blood, hepatocytes detoxifying–regulating sugar–making bile. Fatty liver, hepatitis, cirrhosis, jaundice.
Gut Ruột & Hệ vi sinh
Villi absorbing nutrients, the gut microbiome fermenting fiber–making vitamins. Dysbiosis, malabsorption, enteritis.
Endocrine Hệ nội tiết
Pituitary–thyroid–adrenal–pancreas secreting hormones through the blood to targets, negative feedback keeping balance. Hyper/hypothyroidism, stress, diabetes.
Reproductive Hệ sinh sản
The 28-day menstrual cycle, follicle→ovulation→corpus luteum, the uterine lining thickening–shedding; fertilization, blastocyst implantation.
Nose Mũi & Khứu giác
Odor molecules dissolving in mucus bind olfactory cilia, neurons reporting to the olfactory bulb. Congestion, anosmia, adaptation, sneezing.
Tongue Lưỡi & Vị giác
Tongue papillae hold taste buds, substances dissolved in saliva trigger 5-taste receptors (sweet/sour/salty/bitter/umami). The ‘taste map’ is a myth; spicy is pain.
Sleep Giấc ngủ & Nhịp sinh học
A night through ~90-minute NREM/REM cycles, brain waves shifting by stage; the 24h melatonin–cortisol body clock. Insomnia, jet lag.
Embryo Phát triển phôi thai
From 1 cell → a baby: zygote, blastocyst, implantation, 3 germ layers, organ formation and growth across 3 trimesters.
Blood Máu & Tạo máu
Red cells carrying O₂, white cells for immunity, platelets for clotting; bone marrow making blood. With anemia, leukemia, hemophilia.
Lymphatic System Hệ bạch huyết
Returning interstitial fluid to the veins, nodes filtering & activating immunity. With lymphedema, lymphadenitis, lymphoma.
