s2 Examplify glomerulus\

Question 1

in response to haemorrhage which is activated to cause dec in GFR

Answer 1

sympathetic NS

Question 2

if mean arterial pressure increases, what happens in glomerular capillaries?

Answer 2

constriction of afferent arteriole

to prevent an inc in pressure in glomerular capillaries

Question 3

inc in pressure in bowman space - how does this affect net glomerular filtration pressure and GFR?

Answer 3

DEC

Question 4

if glomerular oncotic pressure decreased what would happen to GFR?

Answer 4

increase

as oncotic pressure in the glomerulus opposes filtration

Question 5

what would happen to GFR if tubular hydrostatic pressure increases?

Answer 5

decrease

> as its an opposing force to the capillary hydrostatic pressure in the glomerulus

Question 6

what occurs in conditions of low BP to maintain glomerular filtration?

Answer 6

efferent arteriole constricts to a greater degree than afferent arteriole (AA relax)
> glomerular pressure increase

Question 7

what is an abnormally high blood creatinine with low urinary creatinine concentration an indicator of?

Answer 7

decreased kidney function
