The countercurrent multiplier system
WebThe counter-current multiplier or the countercurrent mechanism is used to concentrate urine in the kidneys by the nephrons of the human excretory system. The nephrons involved in the formation of concentrated urine extend all the way from the cortex of the kidney to the medulla and are accompanied by vasa recta. Webcountercurrent multiplier the amount of cross-transport in a COUNTERCURRENT-EXCHANGE system per unit distance, being a function (= multiplication) of the total …

WebCountercurrent Mechanism Countercurrent means that fluid flows the opposite directions through side-by-side segments of the SAME tube by a hairpin rurn - consists of long Loops … 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. The ability to concentrate urine is also present in
WebThe Countercurrent Mechanism partially contributes to generation of the corticopapillary osmotic gradient and is the product of juxtamedullary nephrons which possess long loops of Henle that extend far into the renal medulla. Mechanism Overview
WebThe loop is a countercurrent multiplier system in which fluids move in opposite directions through side‐by‐side, semi‐permeable tubes.
