The mechanism of water reabsorption by the renal tubules is

The correct answer is OSMOSIS.

Explanation:

The option attached to this question are as follows:

A. Filtration.

B. Osmosis.

C. Active transport.

D. Co-transport with sodium ion.

Water re-absorption is the process by which water, which was lost during glomerular filtration re-enter the blood. The process typically occurs at the proximal convoluted tubule of the nephron. The process occurs by mean of osmosis, which is a form of passive transport. Re-abosorption usually occur based on the concentration gradients that exist in the convoluted tubule, movement takes place from the high concentration in the tubule to the low concentration in the blood capillaries that are surrounding the tubules.
