The Heart: An Incredible Life Pump

Did you know your heart beats over 100,000 times a day without you even thinking about

it? Let’s dive into the incredible journey of blood and see how this amazing

pump keeps you alive. Here's what actually happens. Your heart has four chambers.

Two on top called atria and two on bottom called ventricles. Blood that's low on oxygen comes

back from your body into the right side. The heart squeezes and pushes this blood to your lungs

where it picks up fresh oxygen. Then it returns to the left side of your heart.

This is the strongest part because it has to pump that oxygen rich blood out to your entire

body through your arteries. The whole cycle takes less than a minute.
