Main control of peripheral resistance occurs
Web53. The main control of peripheral resistance occurs in the arteriole 54. The vascular pressure that declines from roughly 35 mm Hg to about 18 mm Hg is the capillary … WebWhen blood pressure rises too high, baroreceptors fire at a higher rate and trigger parasympathetic stimulation of the heart. As a result, cardiac output falls. Sympathetic stimulation of the peripheral arterioles will also decrease, resulting in vasodilation. Combined, these activities cause blood pressure to fall.
