The journey to life
Hundreds of millions set out. One arrives. From a sperm cell to the egg, the egg into a tiny person, and nine months later a newborn: thirteen chapters.
Endo-View · Simulations
Follow one thing through the body
Each simulation follows a single cell, molecule or signal at true scale, with every number from the research and every one tagged as measured, estimated or drawn.
The size comparer
A hair, an egg, a blood cell, a bacterium and a virus at true scale, with a scale bar. Zoom from a hair to a virus.
My body in numbers
Enter your age: how many times your heart has beaten, how much blood it has pumped, how many breaths you have taken and how many cells have been replaced.
The blood loop
One red blood cell around the body: the heart, the lungs, the body, and back. The whole lap is open, in six chapters: the right side of the heart, the lungs, the left side of the heart, out through the arteries, the muscles and the way back through the veins.
One heartbeat
Inside the heart: the electrical spark, the valves, one beat in slow motion.
One breath
An oxygen molecule from the nose to the lungs and into the blood.
The eyes and seeing
Light through the lens to the retina, and the signal to the brain.
A bite of food
From the swallow to the villi, the liver and the bacteria of the gut: where a mouthful goes, and what happens to it on the way.
DNA
The double helix, how it is copied, how a gene is read into a protein, and how one changed letter matters.
Inside a cell
The nucleus, the packing of two metres of DNA, the mitochondrion's tiny engines and the factory that makes and ships proteins.
A touch becomes a thought
A press on a fingertip, the spike it starts, its jumps along a nerve, the synapse where it passes on, and the place in the brain where it arrives.
Into the heart
The first path down the zoom ladder: from the heart in the atlas to a centimetre of its wall, one muscle cell and one mitochondrion, each at its true size.
