Counter-Current Mechanism
Counter-Current Mechanism: Overview
This topic explains the steps involved in the countercurrent mechanism. It briefs on concurrent and countercurrent flow. We will also learn about the formation of concentrated urine.
Important Questions on Counter-Current Mechanism
Which part of nephron plays an important role in counter current mechanism?
Hypertonic solution is that solution in which water moves out by diffusion.
Gas exchange in the gills of a teleost fish is enhanced by having the blood flow in direction opposite to the direction of water flow, a process known as?
Which of the following statements is/are correct with respect to counter current mechanism?
(A) The flow of filtrate in two limbs of Henle's loops in opposite directions and thus forms a counter current.
(B) It helps in maintaining an increasing osmolarity towards the inner medullary interstitium i.e., 1200 mOsmol L-1 in inner medulla and 300 mOsmol L-1 in the cortex.
(C) The gradient is mainly caused by NaCl and urea.
