Final answer:
The right ventricle in the heart pumps deoxygenated blood to the lungs.
Step-by-step explanation:
The function of the right ventricle in the heart is to pump deoxygenated blood to the lungs. The right atrium receives deoxygenated blood from the body, and then it passes to the right ventricle through the tricuspid valve. The right ventricle contracts and pumps the deoxygenated blood to the lungs through the pulmonary arteries.
