What is the primary job of the right ventricle?

The primary job of the right ventricle is to pump deoxygenated blood to the lungs. In the circulatory system, blood that has already circulated through the body and has delivered oxygen to the organs and tissues returns to the heart, entering the right atrium. From there, the blood moves into the right ventricle, which then contracts to send this deoxygenated blood through the pulmonary arteries to the lungs.

In the lungs, blood receives oxygen and releases carbon dioxide, effectively reoxygenating the blood before it returns to the left side of the heart. This process is crucial for maintaining oxygen levels in the body, making the action of the right ventricle essential for effective respiratory and circulatory functioning.
