Which vessel exits the right ventricle?

• A. Aorta
• B. Pulmonary trunk
• C. Superior vena cava
• D. Pulmonary veins

Answer: (B)

The right ventricle drives blood into the pulmonary circulation through the pulmonary trunk. This main arterial vessel exits the heart from the right ventricle and then splits into the left and right pulmonary arteries to carry blood to the lungs for oxygenation.

In contrast, the aorta leaves the left ventricle to supply the body, the superior vena cava returns deoxygenated blood to the right atrium, and the pulmonary veins bring oxygenated blood from the lungs to the left atrium.
