the primary function of the ascending loop of henle in the kidney
The function of the ascending loop of henle is draw Sodium out of the filtrate. The ability of the ascending loop to actively transport sodium into the surrounding tissue is directly related to the amount of water that can be diffused out of the descending loop of henle. (main factor in water re-absorption)
the ascending loop of henle
Is drained by an efferent arteriole.
The loop of Henle is the U-shaped segment of the nephron located in the kidney. It plays a key role in reabsorbing water and salts from the filtrate to maintain fluid balance in the body. The loop of Henle is composed of a descending and an ascending limb.
In the ascending loop, Na+ (or any solute) is actively pumped out of the tubule. As flow continues up the loop, the tubular concentration decreases as does the interstitial (the fluid surrounding the loop) concentration.Because water is impermeable in the ascending loop, the volume at the bottom of the loop is the same as that entering the distal tubule. At the bottom of the loop, the tubular and interstitial concentrations are equal.The ascending loop of Henle actively pumps sodium and potassium out but water can not follow. This concentrates the water inside the loop of Henle.

(main factor in water re-absorption)
Sodium is primarily reabsorbed in the kidneys, specifically in the proximal tubule and the thick ascending loop of Henle. Around 67-70% of sodium reabsorption occurs in the proximal tubule, while the remaining 25-30% occurs in the thick ascending loop of Henle.
It reabsorbs water from Renal Tubules.
The thick ascending limb of the loop of Henle does not absorb water passively by osmosis. Instead, it actively transports ions like sodium and chloride out of the filtrate, creating a concentration gradient that allows for further water reabsorption in the distal tubule and collecting duct.
absorption of water (from descending limb), absorption of Na+ (from ascending limb)
The loop of Henle is a U-shaped structure in the kidney that plays a crucial role in concentrating urine by creating a concentration gradient in the renal medulla. It consists of a descending and an ascending limb, each with specific functions in reabsorbing water and ions. The loop of Henle is a key component of the nephron, which is the functional unit of the kidney responsible for filtering and processing blood to form urine.
The segment of the nephron that is not permeable to water even in the presence of vasopressin is the ascending limb of the loop of Henle. This segment actively reabsorbs sodium and chloride ions, but water remains impermeable, allowing for the concentration of urine.
