Increase of which molecule will lead to vasodilation?

Angiotensin II

Norepinephrine

O2

CO2

Glucose

During exercise, blood flow is maintained relatively constant to the brain and heart, but is rapidly increased to active skeletal muscles.

Describe the autoregulatory responses responsible for this local control of blood flow.

If Pc=35, πc = 14, πi = 3, and Pi = 0; What is the NDP?

11

14

24

49

52

If the NDP above is on the arterial end of the capillary, and the only change in Starling forces on the venous end are a decrease in capillary hydrostatic pressure to 15, will there be net filtration or net absorption through the capillary?

Would this lead to any clinical symptoms, if so, what?

What sort of pathophysiology (disease) might cause this outcome?

An increase in blood pressure will cause a/an _________ in baroreceptor firing leading to a/an _________ in sympathetic nervous system activity

increase/decrease

decrease/increase

decrease/decrease

increase/increase

stabilization/no change

Describe how the kidney regulates long term control of blood volume and blood pressure.

Describe the body's response to standing from a supine position. Include all changes in blood pressure, venous return, and cardiac output.

Exercise leads to an increase in SNS activation, which leads to vasoconstriction. How do vessels in skeletal muscle compensate for this effect?
