Which statements regarding arterioles are true, and which are false? 0.8 pts True False Arterioles contribute approximately 55% of the total systemic peripheral resistance at rest. Arterioles have a rich parasympathetic nerve innervation In actively metabolizing tissues, local metabolites result in arteriolar vasodilation Sympathetic innervation leads to contraction of smooth muscle in the arteriolar wall, thereby decreasing resistance to flow. Which statements regarding capillaries are true, and which are false? 0.6 pts > True False Capillary walls are subjected to relatively high pressures that cause some very small leakage of plasma across them into the interstitial fluid Flow rates within capillaries are slow enough to allow efficient exchange of gases and nutrients by diffusion. The entry of blood into capillaries is controlled by precapillary sphincters and arterioles
