A map of the human body. Choose a layer, step inside, and tap any part to see where it sits, what it does, and what tends to go wrong there.
The first screen is the whole body. Glowing dots open a region; blue dots go one layer deeper. Tap the chest and the layer with heart and lungs opens; tap the heart again and its four chambers and valves appear. Each part carries its name, its shape, its job, and the illnesses that belong to it.
The systems covered: brain and nerves, the sense organs, heart and vessels, lungs and airways, the digestive organs, kidneys and bladder, bones and joints, and front and back plates of the muscles. The plates are drawn in the grain of old anatomical engravings.
This page is not medical advice. It is drawings and explanations for understanding how the body is put together; if you have symptoms, see a doctor first.
