Question

1. During exercise, the amount of blood that returns to the heart increases dramatically. What change (if any) can be predicted about stroke volume

Answer 1

Due to the increase in the amount of blood that returns to the heart during exercise, the stroke volume increases.

What is stroke volume?

Stroke volume refers to the volume of blood pumped by the left ventricle of the heart per beat.

Factors that affect the stroke volume include:

• contractility
• preload and
• afterload

An increase in exercise increasesthe amount of blood returning to the heart, therefore, the stroke volume increases.
