How Your Heart Works
Like Duolingo, but for How Your Heart Works. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
For the part of you with thirty open tabs that never became anything.
A short one: 11 levels across 2 sections, about 22 minutes end to end, roughly 4 days at five minutes a day. It moves through Listening to the Signs and Inside the Pump. It starts from scratch.

Key ideas in How Your Heart Works
- The pulse is a pressure wave created when the heart contracts forcefully, not the physical arrival of blood that just left the heart
- Arterial walls are elastic and stretch outwards with each surge of pressure from the heart
- A well-conditioned heart muscle pumps a larger volume of blood with each individual squeeze (stroke volume)
- Because each pump moves more blood, the heart needs fewer beats per minute to supply the body's resting oxygen needs
- A healthy heart rhythm naturally fluctuates in sync with breathing rather than ticking like a rigid metronome
- Inhaling prompts the nervous system to speed up the heart, while exhaling engages the brakes to slow it down
- A well-conditioned heart recovers rapidly, dropping significantly in rate within the first two minutes after hard exercise
- A steeper drop indicates the nervous system can quickly dial back heart exertion once the demand ceases
- The top number reflects the peak pressure created when the heart actively contracts
- The bottom number measures the remaining pressure in blood vessels while the heart pauses to refill
- The heart continuously adjusts pumping force to deliver oxygen whenever body demands change
- Routine actions like moving, talking, and feeling stress naturally raise blood pressure temporarily
- A shifting reading across the day shows the cardiovascular system responding normally to daily life
- Flexible arteries expand to absorb the shock of each strong surge from the heart
- When artery walls stiffen, they lose their cushioning effect and transmit harsh, high-pressure shockwaves directly into organs
- Artery walls do not have pain receptors to warn you when excessive pressure causes micro-tears
