Which chamber of the heart pumps blood to the lungs?

The right ventricle is the chamber of the heart that pumps deoxygenated blood to the lungs. This process is part of the pulmonary circulation. When blood returns from the body, it enters the right atrium, moves into the right ventricle, and is then pumped through the pulmonary arteries to the lungs. In the lungs, carbon dioxide is exchanged for oxygen, resulting in oxygenated blood that returns to the heart, specifically to the left atrium. This function of the right ventricle is critical for ensuring that the blood is oxygenated, allowing for efficient gas exchange essential for bodily functions. Understanding the flow of blood through the heart is fundamental to grasping the circulatory system's operation, particularly how the right ventricle plays a key role in transferring blood to the pulmonary system.
