Countercurrent Mechanism In Urine Formation
Body prefers urine that is more concentrated to preserve water. This Countercurrent mechanism helps to reabsorb water from the tubular fluid and produce concentrated urine by using energy to generate an osmotic gradient. This process take place in the loop of Henle and vasa recta of nephron. Henle’s loop has two arms where filtrate flows in opposite directions generating the countercurrent. The flow of blood in the vasa recta also occurs in the opposite direction creating the countercurrent which helps in concentration of urine.
Countercurrent Mechanism – Urine Formation and Steps
The countercurrent mechanism in kidney is a process of concentrating urine. It involves the flow of filtrate in opposite directions in the two limbs of the loop of Henle, which creates an osmotic gradient. This gradient allows the kidneys to reabsorb water from the filtrate and produce concentrated urine.
In this article, we will discuss more about the countercurrent mechanism, the steps involved, how urine is formed, and the multiplication of the countercurrent. You can also find the countercurrent mechanism notes here.
