A real body · six systems
See what you're made of.
A real human body, rebuilt from medical scans. Tour six systems, then take over: turn it, strip it back and click any of 2,000 structures.

01 / 06 · Skeletal system
The frame.
206 bones hold you up, guard your organs and make your blood. Every one here is the true shape of a real bone, down to the 27 in each hand.
02 / 06 · Muscular system
The engine.
More than 600 muscles pull on those bones. Together they make up roughly 40% of your weight, from the great sheets of the back to the six that aim each eye.
03 / 06 · Circulatory system
The river.
A fist-sized heart pushes about 5 litres of blood a minute through arteries out to the body and veins back again. Watch it move.
04 / 06 · Nervous system
The network.
The brain and spinal cord send signals along nerves to every part of you at up to about 120 metres a second.
05 / 06 · Respiratory system
The breath.
Air runs down the windpipe and through airways that divide about 23 times before they reach the air sacs. One lung is glass here so you can see inside.
06 / 06 · Digestive system
The fuel line.
A tube about 9 metres long, from mouth to rectum, breaks food down and takes what you need, helped by the liver, gallbladder and pancreas.
Your turn
Now take it apart.
Isolate a system, ghost the rest, hide a muscle to see what lies beneath, or click any structure to read what it does.
