Question

B) aorta.
C) circle of Willis.
D) femoral artery.

Accepted Answer

Blood pressure is lowest in the inferior vena cava, which is the largest vein in the body and carries deoxygenated blood from the lower body to the heart. Blood pressure is highest in the aorta, which is the largest artery in the body and carries oxygenated blood from the heart to the rest of the body. The circle of Willis is a network of arteries in the brain and does not have a specific blood pressure measurement associated with it. The femoral artery is located in the thigh and has a higher blood pressure than the inferior vena cava.
