The heart is an organ about the size of your fist that pumps blood through your body. It is made up of multiple layers of tissue. Your heart is at the center of your circulatory system.

The four main functions of the heart are:

#Pumping oxygenated blood to the other body parts.

#Pumping hormones and other vital substances to different parts of the body.

#Receiving deoxygenated blood and carrying metabolic waste products from the body and #pumping it to the lungs for oxygenation.

Maintaining blood pressure.
