Answer: There are two pumping systems because the right side receives blood from the body and pumps it to the lungs, and the left side receives blood from the lungs and pumps it through the body. Thereby there are two pumping systems.
Step-by-step explanation:
The heart is an organ that pumps blood throughout the body through the circulatory system. Its function is to supply oxygen and nutrients to the tissues and remove carbon dioxide and waste products.
The heart is divided into two separate pumps. The right side of the heart receives oxygen-poor blood from the veins and pumps it to the lungs, Over there, the blood picks up oxygen and gets rid of carbon dioxide, wich is a waste product. On the other hand, the left side receives oxygen-rich blood from the lungs and pumps it throughout the body. This blood enters the top chamber of the right heart, called the right atrium.
So, the right side of the heart receives blood from the body and pumps it to the lungs. The left side of the heart does the opposite. Thereby there are two pumping systems.
