When blood pressure rises, increased output from the baroreceptors stimulates which center? A)cardioacceleratory B)vasomotor C)respiratory D)cardioinhibitory E)pulmonary
Release of histamines and nitric oxide (NO) A)triggers baroreceptor reflexes. B)stimulates the cardioacceleratory centers. C)promotes increased peripheral resistance. D)triggers the release of EPO. E)causes localized vasodilation.
Regarding endocrine processes in cardiovascular regulation, long-term adjustments A)involve sympathetic responses that adjust cardiac output and peripheral resistance to stabilize blood pressure and blood flow to tissues. B)involve alterations in blood volume that affect cardiac output and the transport of oxygen and carbon dioxide to and from active tissues. C)cause immediate, localized homeostatic adjustments. D)drastically alter blood pressure and blood flow to vital organs. E)involve the release of epinephrine and norepinephrine from the adrenal medullae, which stimulate cardiac output and peripheral vasoconstriction.
Shock is an acute circulatory crisis marked by A)low blood pressure and increased blood volume. B)hypotension and increased tissue perfusion. C)high blood pressure and inadequate peripheral blood flow. D)high blood pressure and decreased tissue perfusion. E)hypotension and inadequate peripheral blood flow.
