How does the loop of Henle help to conserve water?
The kidney conserves water by first diluting urine as it moves through the loop of Henle and then concentrating urine in the distal tubules and collecting ducts (the latter under the influence of antidiuretic hormone or ADH).
What are the two types of loop of Henle?
Anatomically, the loop of Henle can be divided into three main segments: the thin descending limb, the thin ascending limb, and the thick ascending limb (sometimes also called the diluting segment).
How loop of Henle Maximise reabsorb water?
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.
Is the loop of Henle the same as the nephron loop?
In the kidney, the loop of Henle (English: /ˈhɛnli/) (or Henle’s loop, Henle loop, nephron loop or its Latin counterpart ansa nephroni) is the portion of a nephron that leads from the proximal convoluted tubule to the distal convoluted tubule.
Does the loop of Henle reabsorb water?
This part of the nephron is called the loop of Henle. Its main function is to reabsorb water and sodium chloride from the filtrate. This conserves water for the organism, producing highly concentrated urine.
What is the difference between ascending and descending loop of Henle?
The key difference between ascending and descending loop of Henle is that ascending loop of Henle is the thicker segment of the loop of Henle located just after the sharp bend of the loop while descending loop of Henle is the thinner segment located just before the sharp bend of the loop.
What is the function of the ascending and descending loop of Henle?
The descending thin loop is a primary site of water absorption. In contrast, the ascending loop is permeable to ions rather than water.
What is the role of the loop of Henle?
The primary function of the loops of Henle and the thick ascending limb of the distal tubule is the concentration of urine utilizing a principle called ‘countercurrent multiplication. ‘ The medulla possesses a gradient of urea and salt with increasing concentrations of these solutes closer to the papillae.
What is reabsorbed at the loop of Henle?
What is the difference between PCT and DCT?
Proximal Convoluted Tubule (PCT) receives primary urine from glomerulus. Distal Convoluted Tubule (DCT) receives urine from the glomerulus. PCT regulates excretion of urine by absorbing excess water from primary urine. In DCT, water and salts are secreted.
What is the function of the ascending loop of Henle?
The thick ascending limb expresses a sodium-potassium-chloride cotransporter and helps reabsorb approximately a third of the filtered sodium and chloride from the fluid in the tubular lumen into the blood. Other functions of the loop of Henle include: Homeostatic mechanisms to regulate the extracellular fluid volume.
What is absorbed in the ascending loop of Henle?
The loop of Henle is the site of the majority of magnesium absorption from the kidneys. Approximately 60% to 70% of filtered magnesium is reabsorbed in the cortical thick ascending limb of the loop of Henle.
Does the loop of Henle reabsorb more solutes than water?
Reabsorption of water and solutes takes place at different places over the course of the nephron. Reabsorption of solutes more than water takes place along the thick ascending limb of the loop of Henle, distal convoluted tubule and collecting duct.
Which is more coiled PCT or DCT?

|The cells present in the Proximal Convoluted Tubule (PCT) have brush border which is capable of absorption.
|Distal Convoluted Tubule (DCT) is the highly coiled part found in the medulla of the kidney.
What happens in the ascending and descending loop of Henle?
What is secreted in the descending loop of Henle?
The loop of Henle has a thin descending limb, a thick ascending limb and a thin ascending limb. The fluid entering the descending limb contains sodium chloride and other salts, urea and other chemicals that have been filtered out from the blood.
Why is the ascending loop of Henle function impermeable to water?
The ascending loop of Henle function is impermeable to water. In this, sodium chloride is transported from a thick portion of the ascending limb without accompanying water so an osmotic gradient of approximately 200 mosm/kg is generated.
What is the function of the Henle loop?
Alternative Titles: Henle’s loop, nephronic loop. Loop of Henle, long, U-shaped portion of the tubule that conducts urine within each nephron (q.v.) of the kidney of reptiles, birds, and mammals. The principal function of the loop of Henle appears to be the recovery of water and sodium chloride from the urine.
What happens to Na and Cl in the loop of Henle?
The loop of Henle has a descending limb and an ascending limb. As filtrate moves down the loop of Henle, water is reabsorbed, but ions (Na,Cl) aren’t. The removal of water serves to concentrate the Na and Cl in the lumen. Now, as the filtrate moves up the other side (ascending limb), Na and Cl are reabsorbed, but water isn’t.
How does filtrate move down the loop of Henle?
The loop of Henle has a descending limb and an ascending limb. As filtrate moves down the loop of Henle, water is reabsorbed, but ions (Na,Cl) aren’t.
