(07) - Glomerular Filtration

Question 1

Answer 1

A

reason it increases is beacuse when you increase pressure in the glomerulus - whatever protein that leaks through membrane - main reason it increases it because flow is increased

Question 2

Answer 2

B

will be exceted by kindey by secretion (a transport process in tubules)

Question 3

benazepril is an ace inhibitor - inhbits production of Angiotensin II (AGII is a vasoconstrictor)

Answer 3

B

Question 4

Answer 4

B

Question 5

Answer 5

A

Question 6

Answer 6

H

Question 7

on the right is pathologic - get bigger holes - molecules can go through - size of the

so net filtration actually goes down - cause there are are actually less holes - they are just bigger now - so you need increased pressure to compensate for this

Question 8

what is basically happening is you are getting a disruption of the oncotic pressure and the effect of fluid translocation across the capillaries - this results in expansion of intersitium (edema) - disrupts function - GI, kindeys, lungs, brain - everything where edema is starts to fail - if we give to much fluid they do worse cause you are then expanding the interstitial fluid

Question 9

1-4. What four things do you need to have to have nephrotic syndrome?

Answer 9

1. proteinuria
2. hypoalbuminemia
3. edema
4. hyperlipidemia (once compensatory mechanism is that liver starts to increase lipid in blood - response to decrease in oncotic pressure in vasculature)

Question 10
