Which chamber of the heart sends deoxygenated blood to the lungs?

• A. Right Atrium
• B. Right Ventricle
• C. Left Atrium
• D. Left Ventricle

Answer: (B)

The right ventricle is the chamber of the heart responsible for sending deoxygenated blood to the lungs. When blood returns to the heart from the body, it enters the right atrium and then flows into the right ventricle. From the right ventricle, this blood is pumped through the pulmonary artery to the lungs. In the lungs, carbon dioxide is exchanged for oxygen during the process of respiration. This oxygenated blood then returns to the heart, entering the left atrium, and subsequently is pumped out to the rest of the body by the left ventricle. The roles of the other chambers are to transport blood differently. The right atrium collects deoxygenated blood, the left atrium receives oxygenated blood from the lungs, and the left ventricle is responsible for pumping this oxygen-rich blood throughout the body.
