Glomerular Filtration Rate

Question 1

what is the end result of urine formation

Answer 1

filtered blood and excretion of waste

Question 2

describe filtration

Answer 2

filtration: from renal corpuscle to nephron tubules

Question 3

describe reabsorption

Answer 3

reabsorption: from filtrate in nephron to blood

Question 4

describe secretion

Answer 4

from blood to filtrate in nephron

Question 5

what are the three layers of filtration

Answer 5

before fluid in blood plasma can enter the nephron tubule network, it must pass through the three layers of filtration:

1. capillary fenestrae: holes in the glomerular capillaries
2. basement membrane of glomerular capillaries (rich in collagen)
3. inner layer of bowman’s capsule, consisting of podocyted

Question 6

describe the inner layer of Bowmans capsule

Answer 6

inner layer of bownan’s capsule made of podocytes: podocyte processes and pedicels attached to glomerulus and aid in filtration (cell body floats)
