Human Heart: Anatomy, Function & Facts. (Image: © Dreamstime) The human heart is an organ that pumps blood throughout the body via the circulatory system, supplying oxygen and nutrients to the tissues and removing carbon dioxide and other wastes.
In humans, the heart is approximately the size of a closed fist and is located between the lungs, in the middle compartment of the chest. In humans, other mammals, and birds, the heart is divided into four chambers: upper left and right atria and lower left and right ventricles.
The size of the heart is the size of about a clenched fist. The human heart functions throughout a person’s lifespan and is one of the most robust and hardest working muscles in the human body. Besides humans, most of the other animals also possess a heart that pumps blood throughout their body.
