Question 3

What is vascular shunting?

Answer 3

Process that increases blood flow to active areas during exercise by diverting blood away from inactive areas; achieved by vasodilation and vasoconstriction.

Question 4

Cardio-respiratory system:

Answer 4

the interaction of the heart and lungs to supply oxygen to muscles during exercise.

Question 5

Vasodilation:

Answer 5

when veins swell up or dilate; widening of the internal diameter (lumen) of the blood vessel to allow increased blood flow.

Question 6

Vasoconstriction:

Answer 6

when veins shrink down; narrowing of the internal diameter (lumen) of the blood vessel to decrease blood flow.
