Answer 6

H+ ions are actively secreted into the filtrate

Question 7

Any increase in cretenine level increase in abnormal kidneys functioing

Answer 7

True

Question 8

Kidney

Question 10

Towards the center of outer convex surface of kidney is a notch called helium

Answer 10

Wrong towards inner concave surface

Question 11

Inner to helium is broad funnel shaped spaced calle

Answer 11

Renal pelvis

Question 12

Renal tubule begins with cup shaped like structure called

Answer 12

Bowman capsule

Question 13

The DCT of many nephrons opens into the straight tube like structure called collecting duct which converge and opens into the renal pelvis through medullary pyramids

Answer 13

Correct

Question 14

Peritubular capillary

Answer 14

Efferent areteriole rmmerging from glomerulus form a fine capillary network around renal tubule

Question 15

Roughly one fifth of cardiac out put is pump by each ventricle if heart in minute

Answer 15

Correct

Question 16

Glomerulus hydrostatic pressure is oppose by

Answer 16

Blood osmotic pressure and capsular hydrostatic pressure

Question 17

GFR in healthy individual

Answer 17

125ml/min and 180 liter/day

Question 18

Absorption of water is maximum in

Answer 18

Glomerulus

Question 19

Renini is released by

Answer 19

JG

Question 20

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

Answer 20

Correct

Question 21

Reabsorbtion is mimmium in

Answer 21

Ascending limb of loop henle

Question 22

Maintance of high osmolarity in medullary interstitium

Answer 22

Loop of henle

Question 23

Conditional absorbtion of water and NA is in

Answer 23

DCT

Question 24

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

Answer 24

Maintaining an increasing osmolarity toward the inner medulla interstitium

Question 25

Small amount of urea enter in

Answer 25

Thin segment of ascending limb of loop henle

Question 26

Presence of such interstital gradient helps in

Answer 26

Easy passage of water from the collecting tubule

Question 27

ADH facilitate water reabsorbtion from distal part of tubule and thereby preventing diuresis

Answer 27

Wrong reabsorbtion from latter part of tubule

Question 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

Answer 28

Both correct and correct explanation

Question 29

Angiosten 2 also activates

Answer 29

Release of aldosterone

Question 30

Aldosterone cause the reabsorbtion of NA and water from the ________ part of tubule

Answer 30

Distal part

Question 31

Saliva secreted nitrogenous waste

Answer 31

Urea
