2. During exercise, an increase in sympathetic nervous system activity leads to constriction in most vascular beds. This does not happen in the contracting (active) skeletal muscle, due to the effect of locally produced metabolites. What would be the consequence to the cardiovascular system if vasoconstriction did occur in the active muscle? a) there would be a decrease in total peripheral resistance b) there would be an increase in total peripheral resistance c) there would be a dangerous decrease in mean arterial pressure d) there would be no change in mean arterial pressure since arteries are distensible
