Detailed explanation-1: -Overview. Your heart is divided into two separate pumping systems, the right side and the left side. The right side of your heart receives oxygen-poor blood from your veins and pumps it to your lungs, where it picks up oxygen and gets rid of carbon dioxide.

Detailed explanation-2: -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.

Detailed explanation-3: -Heart: The human heart is a muscular organ about the size of a fist, extending just behind and slightly left of the breast bone. It consists of four chambers, two atria, and two ventricles. The heart pumps blood along with the network of arteries and veins forming the ‘Cardiovascular system’.
