All of the following cardiac measurements will increase during exercise except ________.
A) end-diastolic volume
B) end-systolic volume
C) stroke volume
D) cardiac output
End-diastolic Volume
The volume of blood in the ventricles at the end of diastole, immediately before contraction.
End-systolic Volume
This is the volume of blood left in the ventricle at the end of systole, just before the heart fills again during diastole.
Stroke Volume
The amount of blood pumped by the left ventricle of the heart in one contraction, indicating cardiac efficiency.

Final Answer :
B
Explanation :
During exercise, the heart pumps more efficiently, leading to an increase in end-diastolic volume, stroke volume, and cardiac output as the body demands more oxygen. However, end-systolic volume decreases because the heart is pumping out more of the blood it contains with each beat.
