A) increased circulation to the brain. What does the medullary ischemic reflex results in. A) increased circulation to the brain. B) reduced circulation to the brain.

D) increased circulation to the adrenal medulla. E) hormone secretion by the adrenal medulla when perfusion drops. Hyperemia is an active engorgement of vascular beds with a normal or decreased outflow of blood. It occurs because of increased metabolic activity of tissue that results in localized increased concentrations of co 2, acid, and other metabolites. These cause a local stimulus for vasodilation and increased flow (hyperemia). The causes of hyperemia vary depending on whether it is active or passive. Causes of active hyperemia include: Reactive hyperemia is the transient increase in organ blood flow that occurs following a brief period of ischemia (e. g. , arterial occlusion). Reactive hyperemia occurs following the removal of a tourniquet, unclamping an artery during surgery, or restoring flow to a coronary artery after recanalization (reopening a closed artery using an angioplasty balloon or clot.
