What takes blood out of the left ventricle?

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

Answer: (A)

The left ventricle pumps blood into the aorta, the main artery that carries oxygen-rich blood to the entire body. Blood leaves the heart through the aortic valve into the aorta, then travels through systemic circulation. The other vessels have different roles: the pulmonary trunk comes from the right ventricle to the lungs, the superior vena cava returns blood to the right atrium from the upper body, and the coronary sinus drains coronary venous blood into the right atrium. So, the vessel that takes blood out of the left ventricle is the aorta.
