Most 3D anatomy apps stop at the organ. Corpus keeps going: into the nephron, onto the membrane of one cell, down to each transporter, with its gene, what it carries, the hormones that tune it, the drugs that block it and the diseases that break it.
Runs in your browser. No account, no tracking, works offline once installed.
Every level is clickable and every structure explains itself. Breadcrumbs keep you oriented, and search jumps straight to any gene, drug or disease.
The heart beats, filtrate concentrates, oxygen loads and nerves fire. Move a slider and the whole system responds, from urine output to cardiac output.
Each pump, channel, carrier and receptor sits on the membrane where it is actually expressed, moving the right ions in the right ratio.
Turn on furosemide, ADH, Bartter syndrome or cystic fibrosis and watch which transporters stop, speed up or appear, with the clinical consequences explained.
Every level has a step-by-step tour that highlights each structure while it explains it. Turn on narration and it reads itself aloud.
Find the spleen on the 3D body, or locate NKCC2 on a cell with every label hidden. Score yourself as you go.
Type a gene (SLC12A3), a drug (amiloride) or a disease (Liddle) and land on the exact transporter, with the condition already applied.
Each one is a quantitative teaching model with clinical presets.
Valves, chamber volumes and the conduction wave, synchronised with a Wiggers diagram and pressure–volume loop.
A countercurrent model of a juxtamedullary nephron. Tubular fluid changes colour with osmolality and thins out as it is reabsorbed.
Endothelium, basement membrane and podocytes with live Starling forces.
An alveolus with oxygen and CO₂ crossing the barrier, the oxyhaemoglobin curve and capillary equilibration.
The Hodgkin–Huxley equations integrated live in your browser, with channel gates you can watch open and close.
In the myocyte and pacemaker cell, an action-potential trace drives every channel in real time.
Proximal tubule S1–S2 and S3, thin descending and ascending limbs, thick ascending limb, macula densa, DCT, principal cell, α- and β-intercalated cells, inner medullary collecting duct. Plus the organ, nephron and glomerular barrier.
Ventricular cardiomyocyte and sinoatrial pacemaker cell, plus the cardiac cycle with conduction system and valves.
Ciliated airway epithelial cell (CFTR, ENaC), plus the alveolus with type I and II pneumocytes and macrophages.
Gastric parietal cell, villus enterocyte, crypt secretory cell and hepatocyte (bile secretion).
Pancreatic β cell (insulin secretion), pancreatic duct cell (HCO₃⁻) and thyroid follicular cell.
Axon membrane with Nav and Kv channels in a live Hodgkin–Huxley model, and peripheral nerves, cord and brain in 3D.
Corpus is a set of static files with no server and no account. Pick whichever way suits you.

Download Corpus.zipTransporter locations, stoichiometries, genes, regulation and pharmacology follow standard physiology and pharmacology teaching. The quantitative models (urine concentration, Starling forces, the Wiggers diagram, gas exchange) are simplified teaching models that reproduce textbook values, not patient simulators.
No. It is a schematic model built from simple shapes so it stays small and fast. Positions and relationships are right; shapes and proportions are approximate. The detailed accuracy lives in the organ, tissue and cell levels.
Medical, nursing, pharmacy and physiology students, teachers who want something to project, and anyone curious about how the body works at the level of molecules.
No. Corpus is for learning. It does not give medical advice and should not guide diagnosis or treatment.
