Answer:
a. It is the volume ejected per beat
d. Mathematically, stroke volume equals EDV-ESV.
Explanation:
Stroke volume refers to the volume of blood which is expelled out by the left ventricle of the heart to the body.
The stroke volume can be measured with the echocardiogram which measures the EVD or End-diastolic volume which represents the volume before the contraction of the ventricle and the ESV or End-systolic volume which represents the residual volume after the contraction.
The Stroke volume is calculated by the difference between the EDV and ESV. The stroke volume for a normal person is measured is 70 mL per sec.
Thus, the selected option is correct.
