The purpose of your heart is to pump blood to the organs and tissues of your body that need the oxygen and nutrients it carries. Oxygen-rich blood is pumped out of the left side of your heart (shown on the right in the diagram) into the arteries to these tissues and organs.
Blood that has delivered its nutrients and oxygen and is in need of oxygen comes back to your heart in the veins and enters the right hand side of the heart (on left of diagram). This blood which is in need of oxygen (so-called deoxygenated blood) is sent to your lungs to pick up oxygen and get rid of carbon dioxide.
Your heart pumps all day to circulate blood around the body. On average, a red blood cell in the circulation will pass through the heart every 45 seconds. If you start to exert yourself your heart will start to pump faster to supply your working muscles with the increased amount of oxygen and nutrients they need. The heart is a muscle too, and to enable it to pump effectively, it has its own blood supply bringing it oxygen.
