- A. Aorta
- B. Veins
- C. Arteries
- D. Capillaries
Explanation
Blood pressure is the pressure exerted by the blood on the walls of the blood vessels. The aorta is the largest artery of the body that carries oxygenated blood from the left ventricle of the heart to the rest of the body. Blood pressure is highest in the aorta because this is the location where the blood is ejected from the heart with the greatest force. As the blood moves away from the heart, the blood pressure gradually decreases

Questions compare pressure and blood flow in each vessel and distinguish pulmonary vessels, which carry blood to and from the lungs, from systemic vessels.
