Understanding Your Heart
How Your Heart Works
Your heart beats thousands of times per day, pumping dozens of gallons of blood each hour. It pumps blood through your lungs, where the blood is replenished with oxygen, and pumps it back out to the rest of your body. The heart has four chambers; the upper two chambers are called the left atrium and right atrium, and the lower two are called the left ventricle and right ventricle. Heart valves are the doorways between these chambers. They open to let blood pass from one chamber to the next, closing quickly between heartbeats so blood does not flow backward
