The main function of the heart is to pump blood through the body. Also to provide oxygen rich blood required to live. The heart is made up of four different blood filled areas or chambers. There are two chambers on the top are the left and right atrium. The ones at the bottom are left and right ventricles.
The de oxygenated blood enters the heart through the right atrium. It then flows into the right venricle and gets pumped to the lungs. Where it gets oxygentated again.
