Question

what is selective reabsorption?

Answer 1

Heya!

Ur answer goes like this =>

SELECTIVE REABSORPTION

Selective reabsorption is the process whereby certain molecules, after being filtered out of the capillaries along with nitrogenous waste products and water in the glomerulus, are reabsorbed from the filtrate as they pass through the nephron. Selective reabsorbtion occurs in the PCT.

Answer 2

Explanation:

$\huge \underline \pink{Selective\: Reabsorbtion:}$

➛Ultra filtration is non selective therefore the glomerular contains both waste product and essential solute.

➛Absorbtion of useful essential substances from glomerular filterate by the epethelium of nephron.

➛Reabsorbtion occurs in all the part of nephron - PCT, loop of Henley, DCT, and collecting duct.

➛Majority of reabsorbtion occurs in PCT.

➛It is coiled hence glomerular filterate pass through it very slow for reabsorbtion epithelial cell's possess abundant mitochondria and microvilli.

➛Microvilli increases absorbtion surface.

➛More than ⅔rd volume of glomerular filterate is absorbed in PCT.

➛Reabsorbtion occurs by both active and passive process.
