Effect of Afferent and Efferent Arteriolar Constriction on Glomerular Pressure

Question 1

What pressure is the main determinant of (Glomerlular Filtration Rate (GFR)?

Answer 1

Glomerular hydrostatic pressure

Question 2

If you constrict AFFERENT arteriole, order of next steps

Answer 2

1. Increase resistance
2. Decrease blood flow
3. Decrease glomerular hydrostatic pressure
4. DECREASE GFR

Question 3

If you constrict EFFERENT arteriole, order of next steps

Answer 3

1. Decrease blood flow (causes backup)
2. Increase glomerular hydrostatic pressure
3. INCREASE GFR

Question 4

Is Bowman’s Capsule Hydrostatic Pressure usually a major regulator of GFR?

Answer 4

NO

Question 5
