Define cardiovascular system
the interaction of the heart and lungs to supply oxygen to muscle during exercise.
to do with the heart, blood and blood vessels working together.
when veins swell up or dilate; widening of the lumen of the blood vessel to allow for increased blood flow.
when veins shrink down; narrowing of the lumen of the blood vessel to decrease blood flow.

Define vasoconstriction
the interaction of the heart and lungs to supply oxygen to muscle during exercise.
to do with the heart, blood and blood vessels working together.
when veins swell up or dilate; widening of the lumen of the blood vessel to allow for increased blood flow.
when veins shrink down; narrowing of the lumen of the blood vessel to decrease blood flow.

Define vascular shunting
Process that increases blood flow to active areas during exercise and away from inactive areas.
