Accepted Answer

A) True 
 B)False

Question 11

How do respiratory movements and skeletal muscle contraction affect circulation?

Accepted Answer

A)  They are synergistic because both assist circulation by squeezing and "pumping" venous blood.

D)  Both synergistically increase blood pressure by stimulating the sympathetic nervous system to vasodilate arteries. 
E)  all of these
