Question

Define Counter current multiplier and counter current system composed of vasa recta​

Answer 1

Answer:

Answer:The function of the countercurrent multiplier is to produce the hyperosmotic Medullary Interstitium. The ADH promotes water reabsorption through the walls of the distal convoluted tubule and collecting duct. ... The function of theCountercurrent exchanger “vasa recta” is to maintain hyperosmolar medulla.

Answer 2

Explanation:

A countercurrent mechanism system is a mechanism that expends energy to create a concentration gradient.

It is found widely in nature and especially in mammalian organs. For example, it can refer to the process that is underlying the process of urine concentration, that is, the production of hyperosmotic urine by the mammalian kidney.[1] The ability to concentrate urine is also present in birds.[1]

Countercurrent multiplication is frequently mistaken for countercurrent exchange, a similar but different mechanism where gradients are maintained, but not established.
