Which of the following statements is/are true?

(A) The kidneys remove about 180L of fluid per day from the body. The other 1% is filtered.

(B) Urea, Uric Acid, and creatinine are nitrogenous wastes that are removed from the kidney

(C) Reabsorption is the movement of molecules in the nephron back into the capillaries

(D) Secretion is the movement of molecules from the body into the nephron tubule before

The correct answer is (C) Reabsorption is the movement of molecules in the nephron back into the capillaries

Explanation:

Reabsorption is the transfer of water and solutes molecules from the tubules of the nephron to the capillaries surrounding the tubules. This reabsorption is necessary to maintain the osmotic balance and volume of blood in the body.

Most of the reabsorp[tion take place in the PCT region of the nephron. Almost 100% of glucose is reabsorbed here. Reabsorption of water, ions, hormone, vitamins, urea, etc also takes place here. Reabsorption of some molecule also takes place in Henle loop, DCT, and collective duct.

Therefore the correct answer is c.
