Your body's hardest-working pump, explained simply

Introduction

The heart is a powerful muscle that works nonstop throughout your life, pumping blood to every part of your body.

The heart has four chambers. With each beat, blood travels to the lungs for oxygen and then flows to the rest of the body.

Blood delivers oxygen and nutrients and removes waste. Without circulation, organs cannot survive.

An internal electrical system controls the timing of each heartbeat, even when you are asleep.

Movement, rest, and balanced nutrition all affect how efficiently the heart works.

The heart is not just a symbolit is a tireless pump that keeps every cell alive.
