blood pressure regulation Flashcards
arteries
pressure absorption
arterioles
blood distribution
capilleries
exchange
venules
blood drainage
veins
blood reservoir
windkessel effect
bulging of the walls to keep pressure from going sky high or really low
blood flow
the amount of blood that passes per time unit
activated B2 receptor
vasodilation
activated A1 receptor
vasoconstriction
MAP is affected by
driving force, reservoir and conten (blood volume)
autoregulation
local control loop keeping pressure relatively constant
autocoids
local control loop, locally secreted substances causing vasoconstriction/vasodilation
baroreceptor reflex
systemic control loop, maintains BP in response to changes
RAAS
controls blood vessel diameter, regulates volume
