Which chamber of the heart is responsible for sending deoxygenated blood to the lungs?

• A. Left atrium
• B. Left ventricle
• C. Right atrium
• D. Right ventricle

Answer: (D)

The right ventricle is responsible for sending deoxygenated blood to the lungs. This chamber receives blood that has already circulated through the body and is low in oxygen, coming from the right atrium. Once the right ventricle contracts, it pumps this deoxygenated blood through the pulmonary arteries to the lungs. In the lungs, carbon dioxide is exchanged for oxygen, refreshing the blood before it returns to the left side of the heart for distribution to the body. Understanding the function of the chambers of the heart is crucial for grasping how the circulatory system operates, particularly the flow of blood between the heart and lungs.
