Question

Quizplus · Accepted Answer

[VIII C, D, E 2, F]. Blood flow to the brain is autoregulated by the $\mathrm{PCO}_{2}$. If metabolism increases (or arterial pressure decreases), the $\mathrm{PCO}_{2}$ will increase and cause cerebral vasodilation. Blood flow to the heart and to skeletal muscle during exercise is also regulated metabolically, but adenosine and hypoxia are the most important vasodilators for the heart. Adenosine, lactate, and $\mathrm{K}^{+}$are the most important vasodilators for exercising skeletal muscle. Blood flow to the skin is regulated by the sympathetic nervous system rather than by local metabolites.
