Q

Glomerulus hydrostatic pressure is oppose by

A

Blood osmotic pressure and capsular hydrostatic pressure

17
Q

GFR in healthy individual

A

125ml/min and 180 liter/day

18
Q

Absorption of water is maximum in

19
Q

Renini is released by

20
Q

Reabsorbtion of water also occur passively in the initial segment of nephron

21
Q

Reabsorbtion is mimmium in

A

Ascending limb of loop henle

22
Q

Maintance of high osmolarity in medullary interstitium

A

Loop of henle

23
Q

Conditional absorbtion of water and NA is in

24
Q

The proximity between between loop of henle and vesa recta help in

A

Maintaining an increasing osmolarity toward the inner medulla interstitium

25
Small amount of urea enter in
Thin segment of ascending limb of loop henle
26
Presence of such interstital gradient helps in
Easy passage of water from the collecting tubule
27
ADH facilitate water reabsorbtion from distal part of tubule and thereby preventing diuresis
Wrong reabsorbtion from latter part of tubule
28
A= ADH can also act affect the kidney function by its constritory effect on blood vessel R= an increase in blood pressure can increase the glomerulus blood flow and thereby the GFR
Both correct and correct explanation
29
Angiosten 2 also activates
Release of aldosterone
30
Aldosterone cause the reabsorbtion of NA and water from the ________ part of tubule
Distal part
31
Saliva secreted nitrogenous waste
Urea
