An increase in afterload will result in a(n)
a. decrease in heart rate.
b. increase in heart rate.
c. decrease in stroke volume.
d. increase in cardiac output.
e. increase in stroke volume

Option C.

Explanation:

Afterload is defined as the pressure exerted by the heart that work against to eject blood during systole or ventricular contraction.

Afterload is said as proportional to the average arterial pressure. when systemic vascular resistance and aortic pressure are increased, that results increase in afterload by ventricular dilation and by aortic valve stenosis. As a result in the increased afterload, there is an increase in end-systolic volume and a decrease in stroke volume.

Hence, the correct option is C.

answer:

i believe the answer is d).

explanation:

i think this is because you are tearing apart the muscle, and then when you eat, the muscle re-heals, making itself even stronger.

edit: i put b) before but i meant to put d). sorry for the incorrect answer.
