Given below are two statements.

Statement I  :  The countercurrent mechanism is the special mechanism in our kidney that helps in the production of concentrated urine.

Statement II : The flow of filtrate in the Henle's loop and the flow of blood in vasa recta are in a countercurrent pattern.

In light of the above statements, choose the correct answer from the options given below.

Both statement I and statement II are correct.

Statement I: "The Countercurrent mechanism is the special mechanism in our kidney which helps in the production of concentrated urine."

Explanation: This statement is true. The countercurrent mechanism is a physiological process in the kidney that enables the production of concentrated urine. It involves the countercurrent exchange of ions and water between the ascending and descending limbs of the nephron loop (loop of Henle), which allows for the concentration of solutes in the medullary interstitium and the reabsorption of water.

Statement II: "The flow of filtrate in the Henle's loop and the flow of blood in vasa recta are in a Countercurrent pattern."

Explanation: This statement is also true. The flow of filtrate in the Henle's loop (ascending and descending limbs) and the flow of blood in the vasa recta, the capillaries surrounding the nephron loop, are indeed arranged in a countercurrent pattern. This arrangement facilitates the exchange of solutes and water between the filtrate and the blood, enhancing the kidney's ability to concentrate urine and maintain osmotic balance.
