About the Heart

How the Heart Works

A healthy heart beats around 100,000 times a day. The heart's job is to supply the body with oxygen-rich blood. The heart has four chambers. Blood is pumped through the four chambers with the help of four heart valves.

What Heart Valves Do

Heart valves open when the heart pumps to allow blood to flow. They close quickly between heartbeats to make sure blood does not flow backward. Any trouble in this normal flow will make it hard for the heart to pump the blood where it needs to go.
