WebJun 19, 2024 · Stimulation-induced increases in cerebral blood flow and local capillary vasoconstriction depend on conducted vascular responses. Functional … WebHPV or Hypoxic Pulmonary Vasoconstriction refers to the constriction of the minor pulmonary arteries in response to low levels of oxygen, thus helping in maintaining ventilation/perfusion ration. This reaction is quite contrary to that presented by the systemic circulation wherein a scarcity of oxygen leads to vasodilation.
