Is selectivity needed for filtration to occur? Why or Whynot?

What would happen to the filtration rate if you were to applypressure to the filtration system?

What might happen to the filtration membrane if the water pressureis too high?

What might this be of concern to people who have both kidneydisease and high blood pressure?

Blockage of the urinary tract tends to cause decreased GFR (glomerular filtration rates), while nephritis and glomerular damage tend to increase filtration rates. Explain these results based on the net filtration equation for the kidney that relates HPg, HPc, OPg, and OPc. What effect would dehydration have on GFR and why? How would the kidney respond to this? Be sure to include what, if anything, would happen on the local, hormonal, and autonomic levels of control in response to dehydration. How would this be different in someone who was taking ACE inhibitors for high blood pressure? What would happen to the GFR in someone who has protein deficiency?

A.What happened to the following as the afferent radius increased?

- glomerular pressure

- glomerular filtration rate

- urine volume

B. If the efferent radius increased and the afferent radius stayed the same, would you see different or the same effects? Why?

C. What does the “beaker pressure” represent?

D. What happened to the following as the beaker pressure increased?

- glomerular pressure

- glomerular filtration rate

- urine volume

E. Looking at how urine volume changed with increasing “beaker” pressure, how would this be beneficial to the body?

F. If the body was not able to regulate glomerular filtration rate, what kind of problems would occur because of this increase in pressure?

G. Define renal autoregulation.

H. What are the two mechanisms that help maintain glomerular filtration rate under renal autoregulation?

I. Which mechanism of renal autoregulation does this experiment correspond to?

J. How was urine volume and urine concentration affected in the presence of aldosterone? Explain these results.

K. How was urine volume and urine concentration affected in the presence of ADH? Explain these results.

L. What stimulate the release of aldosterone?

M. What stimulates the release of ADH?

N. How do both of these hormones work in regulating blood pressure?

1. Which of the following would increase glomerular filtration rate? (More than one answer may be correct)

Increased blood pressure

Increased solute concentration in the bowman capsule

Increased solute concentration in the blood

Decreased ADH

2. Explain the concept of a countercurrent multiplier system and how it works in the kidneys. What is the importance of this system to the function of the kidneys?

3. Many drugs prescribed to treat high blood pressure actually act on the kidneys. Why would this be a good target?

4. Explain one mechanism by which such drugs could work.
