Final answer:
Intrinsic regulation of blood flow provides localized control of peripheral resistance through mechanisms such as the myogenic response and chemical signals.
Step-by-step explanation:
The statement is true. Intrinsic regulation of blood flow provides localized control of peripheral resistance. Intrinsic regulation refers to the ability of blood vessels to adjust their diameter in response to local factors such as metabolic demand. This regulation is achieved through the myogenic response and chemical signals.
The myogenic response is a protective function that allows the smooth muscle in the walls of arterioles to react to changes in blood flow. When blood flow is low, the smooth muscle relaxes, dilating the vessel and increasing blood movement. When blood flow is too high, the smooth muscle contracts, causing vasoconstriction and reducing blood flow.
Chemical signals also play a role in intrinsic regulation. For example, when metabolic activity increases in a tissue, the release of certain molecules will cause arterioles to dilate, allowing more blood flow to that specific area.
