What is the countercurrent multiplier in the loop of Henle?
The loop of Henle utilizes the countercurrent multiplier system to increase the concentration of solute and ions within the interstitium of the medulla. This ultimately allows the nephron to reabsorb more water and concentrate the urine while at the same time using as little energy as possible.
What is counter-current mechanism in loop of Henle?
A mechanism used by the kidneys, making it possible to excrete excess solutes in the urine with little loss of water from the body. When the filtrate runs in two different directions in the two arms of Henle’s loop, this is known as countercurrent.
What is the counter-current multiplier mechanism?
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.
What is counter-current mechanism explain with diagram?
The countercurrent mechanism is the mechanism that allows for the production of concentrated urine. The Henle’s loop and vasa recta are the backbones of the mechanism. The flow of filtrate through the two limbs of Henle’s loop and blood through the two limbs of the vasa recta are in a countercurrent pattern.
How is a countercurrent multiplier different from a countercurrent exchanger?
– A countercurrent multiplier system involves movement of ions rather than movement of oxygen or heat transfer. – Unlike the other countercurrent systems, a countercurrent multiplier system expends energy in active transport.
What is counter current mechanism Class 11?
Counter current mechanism Filtrate flows in opposite direction through the Henle’s loop and therefore forms a counter current. The descending limb is permeable to water, and the ascending limb is impermeable to water, but permeable to electrolytes.
What is counter current mechanism class 11th bio?
The countercurrent mechanism helps to concentrate the filtrate which occurs in the loop of Henle and vasa recta in the medulla region of the kidney. The flow of fluids in opposite directions is maintained by their flow in the two loops- ascending and descending limbs of the loop of Henle and vasa recta.
How does countercurrent flow work in dialysis?
Hemodialysis removes blood and passes it through an extracorporeal circuit and an artificial membrane, with dialysate running in countercurrent flow next to the blood in the membrane. After the blood is filtered through the membrane, it is returned to the body with a reduced quantity of metabolic waste products.
What is countercurrent diffusion?
Countercurrent exchange is a mechanism occurring in nature and mimicked in industry and engineering, in which there is a crossover of some property, usually heat or some chemical, between two flowing bodies flowing in opposite directions to each other.
