The heart is a vital organ that pumps blood throughout the body, supplying oxygen and nutrients to all the cells. Understanding the internal anatomy of the heart is essential for understanding how it functions. The heart is divided into four chambers: the left and right atria, and the left and right ventricles. The atria receive blood from the body and lungs, while the ventricles pump blood out to the body and lungs.
The heart also has four valves that ensure blood flows in the correct direction. These valves are the tricuspid valve, pulmonary valve, mitral valve, and aortic valve. Each valve opens and closes at specific times to regulate blood flow.
