Which chamber pumps blood to the lungs for oxygenation?

Explanation:
Blood to the lungs for oxygenation is pumped by the right ventricle. The heart handles two separate circuits: pulmonary (to the lungs) and systemic (to the body). The right side drives the pulmonary circuit, receiving deoxygenated blood from the body and launching it into the pulmonary arteries toward the lungs. There, gas exchange occurs and blood becomes oxygenated, returning to the left atrium to enter systemic circulation. The other chambers have different roles: the right atrium collects blood to move to the right ventricle, while the left atrium and left ventricle handle blood that has been oxygenated in the lungs and pump it to the rest of the body.
