Question

multiple choice question
blood flow is fastest in which of these blood vessels?
femoral artery
capillary
aorta
brachial artery

Explanation:

To determine where blood flow is fastest, we recall the properties of blood vessels. The aorta is the largest artery, directly receiving blood from the left ventricle of the heart. Larger diameter and high pressure from the heart's contraction result in the highest blood flow velocity here. Capillaries have very slow flow for exchange, and femoral/brachial arteries are smaller than the aorta.

Answer:

C. Aorta
