2
Q
Cardiovascular
A
To do with the heart blood and blood vessles together
3
Q
Vascular shunting
A
Process that increases blood flow to active areas during exercise by diverting blood away from inactive areas( achieved by vasodilation and vasoconstriction)
4
Q
Vasodilation:
A
when veins swell up or dilate; widening of the internal diameter (lumen) of the blood vessel to allow increased blood flow.
5
Q
Vasoconstriction:
A
when veins shrink down; narrowing of the internal diameter (lumen) of the blood vessel to decrease blood flow
