What role does the right ventricle serve?

The right ventricle is essential in the circulatory system because its primary function is to pump deoxygenated blood to the lungs for oxygenation. This process occurs through the pulmonary arteries. When blood returns from the body, it is low in oxygen and high in carbon dioxide, and the right ventricle propels this deoxygenated blood toward the lungs. In the lungs, carbon dioxide is released, and oxygen is absorbed into the blood, preparing it for transport to the rest of the body by the left side of the heart.

The other options pertain to functions associated with different parts of the heart. For instance, the left ventricle is responsible for pumping oxygenated blood to the body, while the right atrium receives deoxygenated blood from the body, and the left atrium receives oxygenated blood from the lungs. Understanding the specific roles of each heart chamber clarifies the functions they serve in maintaining efficient blood circulation.
