Which organ in the human body is primarily responsible for pumping blood? 🔊
The organ in the human body primarily responsible for pumping blood is the heart. The heart is a muscular organ that maintains blood circulation throughout the body by contracting and relaxing rhythmically. It consists of four chambers: the left and right atria and the left and right ventricles. The heart pumps oxygenated blood from the lungs to the body and returns deoxygenated blood to the lungs for re-oxygenation. Its functioning is vital for overall health, supplying organs and tissues with the necessary nutrients and oxygen.
