Answer 2

The counter-current mechanism

Explanation:

• The counter-current mechanism operating within the excretory organ is that the main adaptation to conservation. There square measure 2 reversible mechanisms within the excretory organ. they're the Henle loop and therefore the vasa recta.

• The Henle loop is that the U-shaped a part of the tubule. Blood flows in opposite directions on either side of the tube and this produces opposite currents.

• The vasa recta is associate degree corticifugal artery that forms a capillary network round the tubules within the nephritic medulla.

• It runs parallel to the loop of Henle and is U-shaped. Blood flows in opposite directions within the 2 organs of the vasa recta.

• As a result, the blood coming into the nephritic medulla within the downhill limb comes into shut contact with the outgoing blood within the ascending limb.
