WebDuring exercise, the cardiac output increases more than the total resistance decreases, so the mean arterial pressure usually increases by a small amount. Pulse pressure, in contrast, markedly increases because of an increase in both stroke volume and the speed at which the stroke volume is ejected.

Web1. We measured the stroke volume of the left ventricle. What was the average stroke volume of the right ventricle at rest and after exercise? The average stroke volume in the experiment for the left and right ventricle was 70 and increased to 106 when exercising. Stroke volume is generally equal in both left and right ventricle. 2.

Men, on average, have higher stroke volumes than women due to the larger size of their hearts. However, stroke volume depends on several factors such as heart size, contractility, duration of contraction, preload (end-diastolic volume), and afterload. Corresponding to the oxygen uptake, women's need for blood flow does not decrease and a higher cardiac frequency makes up for their smaller s…
