Tukuk-OS🫀 The Human Body
Five micro-lessons · about 38 minutes in total
The machine you live in: heart, lungs, brain, gut and the immune war room. Five lessons, about 38 minutes in total — read one at a time; each stands alone.
The five lessons
1. The Pumps in Your Chest
100,000 beats a day, two circuits, and the pressure numbers that mean.
2. Lungs: The Quiet Surface
A folded 70-square-metres of tissue that works because you stop thinking about it.
3. The Brain: Three Pounds of Wiring
86 billion cells talking in electricity and chemistry, and why it rewire itself.
4. Digestion: The Long Chemistry Bench
A seven-metre workbench that turns bread into you, acid-washes invaders, and farms tenants.
5. Immunity: The Learning Army
Two defence layers, and the 230-year-old trick that taught the second one.
