Question

Basic renal processes include?

Select one:

a. Filtration from Bowman's capsule into the glomerulus.

b. Secretion from the tubule into the peritubular capillaries.

c. Reabsorption from the capillaries into the tubular lumen.

d. Filtration from Bowman's capsule into the glomerulus and secretion from the tubule into the peritubular capillaries.

e. None of the choices are correct

Answer 1

Answer e)

None of the choices are correct

Physiology of urine formation take place from 3 steps

1) Glomerular filtration

2) Tubular Reabsorption

3)Secretion

1)Glomerular filtration occurs as blood passes into the glomerulus producing Ultrafiltrate of Plasma not containing proteins which is then filtered from Glomerulus into Bowmans capsule

2)As the filtrate travels along the length of the nephron, the cells lining the tubule selectively, and often actively, take Substances from tubule and it is further reabsorbed into Peritubular capillaries which are lining the tubules

3)Tubular secretion occurs mostly in the PCT and DCT where substances are moved from the peritubular capillary into the lumen of the tubule.

Answer 1) Incorrect correct statement is --> Filtration from Glomerulus into Bowmans capsule

2) Incorrect Correct statement is Secretion from Peritubular capillaries into Tubule

3)Incorrect Correct statement --> Reabsoprtion from tubular lumen into Capillaries .

4) Already explained in 1) and 2)
