How does a proper warm up affect blood flow?
a -- blood flow increases.
b -- blood flow decreases.
c -- blood flow increases and then decreases.
d -- blood flow decreases and then increases.

Correct answer choice is :

A) Blood flow increases.

Explanation:

Blood flow in the brachial vein rises after strong cycling activity. During cycling, blood flow is redistributed from actually stable tissues to running leg tissues. After both activities mean blood stress was maintained despite improved cardiac output.Blood flow is higher when you exercise because of the blood capillaries in your muscles stretch. As these byproducts leave the muscle cells, they make small, thin-walled blood vessels within the tissue to enlarge or expand, which is named vasodilation.
