In an unfortunate accident, a young man is struck in the leg by a bullet that tears through an artery just above his right knee. The subsequent blood loss leads to a rapid drop in blood pressure. Receptors in the aorta monitor blood pressure and send signals to the vasomotor center of the brain. In this case, the vasomotor center will increase its stimulation of smooth muscle in the blood vessels, which will cause them to constrict. This constriction leads to an increase in blood pressure.

What represents the effector in this feedback system?

A) blood vessel diameter

B) receptors in the aorta

C) vasomotor center

D) blood pressure

Answer is D. Blood pressure.

Explanation:

Blood pressure is the pressure of the blood within the arteries, produced by the contraction of the heart muscle.
