How is water reabsorbed in the loop of Henle?
|
|
selective diffusion
|
|
|
osmosis
|
|
|
active transport
|
|
|
co-transport
|
Explanation:
Detailed explanation-1: -As there is no such thing as active transport for water (no water pump), it accomplishes this by reabsorbing electrolytes by active transport and thus dragging water across from the urine and into the blood by osmosis.
Detailed explanation-2: -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.
