The mechanism of water reabsorption by the renal tubules is ____
|
active transport
|
|
osmosis
|
|
filtration
|
|
cotransport with sodium ions
|
Explanation:
Detailed explanation-1: -Water reabsorption is by osmosis through water channels in the membrane. These water channels consist of a family of proteins called aquaporin . At least seven different aquaporin isoforms are expressed in the kidney.
Detailed explanation-2: -Tubular reabsorption of glucose is an important process that occurs in the kidneys to maintain normal blood glucose levels.
Detailed explanation-3: -The main role of the collecting duct is the reabsorption of water, through the action of anti-diuretic hormone (ADH) and aquaporins. ADH is produced in the hypothalamus, and stored in the posterior pituitary gland until it is released.
