Question

Quizplus · Accepted Answer

Local changes within a tissue resulting from increased metabolic activity can produce local arteriolar vasodilation to allow more blood to flow into the tissue. This is known as autoregulation and is the most important factor in matching blood flow with the metabolic needs of a specific tissue. The sympathetic and parasympathetic nervous systems can also play a role in regulating blood flow, but they are not as significant as local autoregulation. Widespread venous vasoconstriction would actually decrease blood flow, not match it with metabolic needs.
