What is the function of the right ventricle in the heart's circulation?

The function of the right ventricle in the heart's circulation primarily involves initiating pulmonary circulation. This chamber is responsible for receiving deoxygenated blood that has returned from the body through the vena cavae. Upon filling, the right ventricle contracts and pumps this blood into the pulmonary arteries, directing it towards the lungs. Here, the blood releases carbon dioxide and picks up oxygen, completing the pulmonary circuit.

The other options mention receiving oxygen-rich blood, pumping oxygenated blood to the body, and collecting de-oxygenated blood. The right ventricle does not handle oxygen-rich blood; instead, that type of blood is managed by the left side of the heart. Additionally, pumping oxygenated blood is a function of the left ventricle, and while the right ventricle collects de-oxygenated blood, its primary role is to propel that blood into the pulmonary circulation.
