A
Vasoconstrict
Resists blood flow
2
Q
During exercise what do the arterioles do related to muscles
A
Vasodilate
Increases blood flow
3
Q
During exercise what do the pre capillary sphincters do related to organs
A
Constrict
Closes capillary beds restricting blood flow
4
Q

A
Dilate
Open capillary beds increasing blood flow
5
