The Regulation of Blood Flow by Local Mechanisms Within a Capillary

Question

The regulation of blood flow by local mechanisms within a capillary bed is called
A) autoregulation.
B) hormonal regulation.
C) hemoregulation.
D) vasoregulation.
E) neuroregulation.

Accepted Answer

The regulation of blood flow by local mechanisms within a capillary bed is called autoregulation. This includes the ability of the vessel to constrict or dilate in response to various factors such as oxygen levels, carbon dioxide levels, and local metabolites. Hormonal regulation involves the release of hormones such as epinephrine or norepinephrine to control blood flow, hemoregulation is not a commonly used term in this context, vasoregulation refers to the regulation of blood vessel size and tone, and neuroregulation involves the nervous system in controlling blood flow.
