Question

Quizplus · Accepted Answer

Autoregulation is the regulation of blood flow by local mechanisms within a capillary bed. This ensures a consistent blood flow to meet the metabolic needs of the tissues. It involves the dilation or constriction of precapillary arterioles and sphincters in response to local factors such as metabolic byproducts, oxygen and nutrient availability, pH, and temperature. Central regulation refers to the regulation of blood flow by the nervous and endocrine systems, while tissue perfusion refers to the delivery of blood to the tissues as a whole.
