The Heart
What's the Heart?
It is a muscle of the size of your fist that acts like a pump. It has four chambers. The two upper ones are called atrium and the two lower ones are called ventricles. They are surrounded by thick walls of muscle that contract to pump the blood. The septum divides the heart into two sides: right and left.
How does the blood goes into our heart?
Blood enters the heart through the right or left atrium. Then it goes into the ventricles.
When the ventricles contract, they push the blood out of the heart.
