During systole there is mechanical contraction of the vascular arteries most notably which part of the heart?
Endocardial surface
What is the purpose of increasing non muscular vascular resistance during exercise; by the sympathetic system?
Helps maintain BP; compensating for the overall dilation of muscular arteries and decrease of TPR
