Meet Your Heart · Heart
It fills, squeezes, relaxes — and repeats, forever.
Your heart doesn't push blood in one long stream. It squeezes, relaxes, then squeezes again — and that steady rhythm is what keeps your blood moving. Fill, squeeze, release: about once a second, for your whole life.
The chambers fill with blood, then contract to push it forward. One-way valves make sure the flow keeps moving in the right direction instead of sloshing backwards.
