Which of the following equations correctly represents ejection fraction?
$SV/EDV$
What is the average ejection fraction?
54%
Which of the following statements is true about the relationship between exercise and stroke volume (SV)?
Heavy exercise causes a dip in SV.
What is the main reason for a decrease in venous return during exercise?
Increased blood flow to the skin
What is the equation for calculating mean arterial pressure (MAP)?
$MAP = \frac{1}{3} \times SBP + \frac{2}{3} \times DBP$
What is the pulse pressure?
Difference between systolic and diastolic blood pressure
