FUNCTIONS OF THE HEART
Arterial blood (red, oxygen-rich blood) flows from the heart to each part of the body to provide oxygen and nutrients. The venous blood (blue, oxygen-poor blood) returns from the body to the heart. The blood then travels through the lungs to exchange carbon dioxide for new oxygen. The heart is a pump, which moves the blood. The arteries and veins are the pipes through which the blood flows. The lungs provide a place to exchange carbon dioxide for oxygen.

Answer
The main function of the heart is to circulate blood throughout the body. It is a chambered organ which is capable to separating oxygenated and deoxygenated blood into different chambers in order to bring "used" blood from the body and send it to lungs to be oxygenated.
