MCAT Question A Day - 8/10/14 - Answer!

The capillary network comprises the greatest cross sectional area of blood vessels in the body with the highest resistance to blood flow. In a healthy individual, the highest blood pressure would most likely be found in:

A.  the aorta
B.  the vena cavae
C.  the systemic capillaries
D.  the pulmonary capillaries

A is correct. Don't let the not-so-subtle physics reference fool you. Bernoulli's equation, which would indicate a greater pressure at the greater cross-sectional area, doesn't work here. You should memorize that blood pressure in a human is greatest in the aorta and drops until the blood gets back to the heart.
