Glomerular filtration

Question 1

What is hydrostatic pressure in capillaries?

Answer 1

Pressure of plasma on capillary wall - pushes plasma out

Question 2

Single nephron glomerular filtration rate

Answer 2

50nl/min

Question 3

How is GFR altered?

Answer 3

A decrease in resistance (vasodilation) causes an increase in blood flow so volume in capillaries is high so hydrostatic pressure increase increase GFR then auto regulation causes an increase in resistance so a decrease in blood flow and hydrostatic pressure so a decrease in GFR
