Question

Quizplus · Accepted Answer

When a person rises quickly from a sitting position, multiple physiological responses occur to maintain blood pressure and prevent a drop in cerebral blood flow. These responses include decreased activity of carotid baroreceptors in response to decreased stretching of the blood vessels, decreased venous return due to increased pooling of blood in the legs, reflex vasoconstriction of peripheral blood vessels to maintain blood pressure, and reflexively elevated heart rate to increase cardiac output. Therefore, all of the given answer choices are correct.
