Blood circulation around the human body is systematically represented in the given diagram.

Overall, it is clear that there are three vital parts in the human body which are crucial in the process.

As per the diagram, blood cells are produced in the bone marrow as required at regular intervals, and are transferred to the circulation path of blood in the body.

As the oxygen level in the blood declines in different body parts, it is pumped to the heart. This blood is termed as ‘deoxygenated blood’ this blood is further pumped to the lungs for oxygenation. After the gas exchange in the lungs, oxygen-rich blood is pumped back to heart.

The oxygenated blood from the heart is then pumped to various parts of the body. Once the body tissues use this oxygen, the blood again becomes deoxygenated. This blood is returned to the heart and then to lungs for purification and the process continues.
