NEET Zoology Excretory Products And Their Elimination Function Of The Tubules MCQs

In which of the following regions of a nephron, does maximum reabsorption of useful substances takes place?

Percentage of electrolytes and water reabsorbed by PCT is

NaCl is transported by ascending limb of Henle’s loop, which is exchanged with

Which one is related to urine concentration in mammals?

Facultative water reabsorption is

Henle’s loop of nephron plays a significant role in maintaining a high osmolarity in

The renal fluid isotonic to the cortical fluid and blood is found in

I. Reabsorption of water occurs passively in the initial segment of nephron,  II. Nitrogenous waste are absorbed by active transport,  III. Conditional reabsorption of $N{a^ + }$ and water takes place in DCT,  IV. DCT reabsorbs glucose,  V. DCT is capable of selective secretion of ${H^ + }$,${K^ + }$ and $N{H_3}$ to maintain pH and $N{a^ + }$ - ${K^ + }$ balance in blood, VI. Substances like glucose, amino acids, $N{a^ + }$, etc, in the filtrate are reabsorbed actively.   Choose the option with incorrect statements
