Which chamber of the heart pumps oxygen-rich blood to the body?

• A. The right atrium
• B. The right ventricle
• C. The left atrium
• D. The left ventricle

Answer: (D)

The left ventricle is tasked with pumping oxygen-rich blood to the body, making it an essential chamber in the circulatory system. After oxygenation in the lungs, blood returns to the heart, entering the left atrium and then flowing into the left ventricle. The left ventricle has a thick muscular wall that allows it to generate the high pressure needed to propel blood throughout the entire body, including to the brain, organs, and extremities. When the left ventricle contracts, it forces this oxygen-rich blood into the aorta, the largest artery in the body, ensuring that all tissues receive the oxygen they need to function properly. This role is crucial for maintaining the body’s overall health and metabolic processes.
