I actually figured it out, but thank you!

Do you still need assistance?

Then I will mark this topic as solved, for the time being. You're welcome.Then I will mark this topic as solved, for the time being. You're welcome.

PhysioEx Exercise 9: Renal System Physiology

Activity 1: What happens to the glomerular filtration rate as the afferent radius is increased?
     The glomerular filtration rate increases, due to the increased blood flow into the glomerulus.

If the efferent radius is increased, what happens to the glomerular filtration rate?
     Glomerular filtration rate (GFR) decreases.

Activity 2: What happened to the glomerular filtration rate as the beaker pressure was increased?
   Glomerular filtration rate was increased.

Why does an increase in pressure result in a faster glomerular filtration rate? Choose all that apply:
     Because the glomerular hydrostatic pressure increased.
     Because the net filtration pressure increased.

Activity 4: In the presence of ADH, what happened to the urine concentration as the gradient concentration was increased?
     The urine concentration increased.

What factor limits the maximum possible concentration?
     The osmolarity of the interstitial gradient.

Activity 5: What happened to the amount of glucose present in the urine as the number of glucose carriers was increased?
     The amount of glucose present decreased.

What would happen if there was more glucose than could be transported by the available number of glucose carrier molecules?
     Glucose would be present in the urine.

Why would we expect to find glucose present in the urine of a diabetic person?
     There is too much glucose in the filtrate to be reabsorbed.

Activity 6: What happened to the urine volume when aldosterone was added?
     The urine volume decreased.

What happened to the urine volume when ADH was added?
     The urine volume decreased greatly.

What happened to the amount of potassium present in urine when ADH was added?
     The concentration of potassium was higher when ADH was present, but the actual amount of potassium in the urine    remained the same.

How would you compare the effects of aldosterone to the effects of ADH?
     They are similar to one another.

Consider this situation: We want to reabsorb sodium ions, but do not want to increase the volume of the blood by reabsorbing water from the filtrate. Assuming that aldosterone and ADH are both present, how would you adjust the hormones to accomplish the task?
     Increase aldosterone / decrease ADH
