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 âbeaker pressureâ 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 âbeakerâ 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?
