Which is the largest artery in the body?

• A. Carotid
• B. Median
• C. Cerebral
• D. Aorta

Answer: (D)

The aorta is the largest artery in the body because it carries all of the heart’s output into the systemic circulation. It starts at the left ventricle, then ascends, arches, and descends as the thoracic and abdominal aorta, giving off major branches to supply the entire body. Its diameter is larger than any other artery, and it handles the highest volume of blood leaving the heart. The carotid arteries are major vessels to the head and neck, but they are narrower than the aorta. The cerebral arteries are smaller arteries that supply the brain. The term median artery isn’t a standard major vessel in human anatomy.
