Baroreceptors:

Answer 6

True

Question 7

True/false

Baroreceptors:

Answer 7

False

Question 8

Baroreceptors:

Answer 8

True
Can change its set point

Question 9

Phasic and tonic firing

Question 10

True/false

Local Control:

Answer 10

True

Question 11

True/false

Local Control:

Answer 11

True

That is how it adjusts the flow

Question 12

True/false

Local Control:

Answer 12

True

Question 13

True/false

Local Control:

Answer 13

True

Question 14

True/False

In a tissue that shows good autoregulation:

Answer 14

False

Pressure changes

Question 15

True/False

​In a tissue that shows good autoregulation:

Answer 15

False

Question 16

True/False

​In a tissue that shows good autoregulation:

Answer 16

TRUE

This is the purpose of autoregulation

Question 17

​In a tissue that shows good autoregulation - flow to the tissue is kept constant

Answer 17

Vascular resistance

Question 18

True/False

In arterioles, vascular smooth muscle:

Answer 18

True

Myogenic

Question 19

True/False

In arterioles, vascular smooth muscle:

Answer 19

True

Question 20

True/False

In arterioles, vascular smooth muscle:

Answer 20

True

Shear stress is the interaction between blood and epithelium when it flows through a vessel
This produces NO which causes vasodilation

Question 21

Answer 21

Passive vasodilation

Question 22

Answer 22

Increase capillary pressure

will actually INCREASE capillary perfusion, not decrease

Net hydrostatic pressure is capillary pressure - interstitial pressure TRUE

No change to oncotic pressure

Question 23

Answer 23

Diffusion

Question 24

Answer 24

The balance between net hydrostatic and net oncotic pressure

Question 25

Also, which is the most important

Answer 25

All 3 affect capillary pressure venous pressure is the most important

Question 26

True/False

Answer 26

There is typically a net filtration or hydrostatic over-oncotic

Question 27

True/False

Answer 27

About 3L per day

Question 28

True/False

Answer 28

False There are places like skin and bone and brain that don't contain lymphatics
