Blood Pressure Regulation Flashcards
True/false
The baroreceptor reflex provides:
True
True/false
The baroreceptor reflex provides:
True
regulates BP by controlling CO and TPR
True/false
The baroreceptor reflex provides:
False
True/false
The baroreceptor reflex provides:
True
That is the regulated variable
True/false
The baroreceptor reflex provides:
False
True/false
Baroreceptors:
True
True/false
Baroreceptors:
False
True/false
Baroreceptors:
True
Can change its set point
True/false
Baroreceptors:
True
Phasic and tonic firing
True/false
Local Control:
True
True/false
Local Control:
True
That is how it adjusts the flow
True/false
Local Control:
True
True/false
Local Control:
True
True/False
In a tissue that shows good autoregulation:
False
Pressure changes
True/False
In a tissue that shows good autoregulation:
False
True/False
In a tissue that shows good autoregulation:
TRUE
This is the purpose of autoregulation
In a tissue that shows good autoregulation - flow to the tissue is kept constant
Vascular resistance
True/False
In arterioles, vascular smooth muscle:
True
Myogenic
True/False
In arterioles, vascular smooth muscle:
True
True/False
In arterioles, vascular smooth muscle:
True
Shear stress is the interaction between blood and epithelium when it flows through a vessel
This produces NO which causes vasodilation
Passive vasodilation
Increase capillary pressure
will actually INCREASE capillary perfusion, not decrease
Net hydrostatic pressure is capillary pressure - interstitial pressure TRUE
No change to oncotic pressure
Diffusion
The balance between net hydrostatic and net oncotic pressure
Also, which is the most important
All 3 affect capillary pressure
venous pressure is the most important
True/False
There is typically a net filtration or hydrostatic over-oncotic
True/False
About 3L per day
True/False
False
There are places like skin and bone and brain that don’t contain lymphatics
