19
New cards
Active Hyperemia
Increase in blood flow in response to an increase in metabolic rate.
20
New cards
Reactive hyperemia
Increase in blood flow in response to supply being blocked for a short period then unblocked.
21
New cards
Blood flow autoregulation
The intrinsic ability of an organ to maintain a constant blood flow despite changes in perfusion pressure.
22
New cards
False
True/False: Metabolic control of blood flow is dependent on ANS regulation
23
New cards
True
True/False: Metabolic control of blood flow is dependent on chemical changes within the tissue.
