Named after its discoverer, the German anatomist Friedrich Gustav Jakob Henle, the loop of Henle's main function is to create a concentration gradient in the medulla of the kidney. ...
The next part of the tubule is highly coiled (the proximal convoluted tubule) and empties into a U-shaped loop which carries the filtered fluid deep down into the medulla and then back again into the cortex. This part of the nephron is called the loop of Henle.
What does loop of Henle mean?
Definition of loop of Henle : the U-shaped part of the nephron of birds and mammals that lies between and is continuous with the proximal and distal convoluted tubules and that functions in water resorption.
Who named the loop of Henle?
In 1942 Werner Kuhn, a physical chemist, proposed that the loop of Henle may be the natural analog of the hairpin countercurrent multiplication system which concentrates urine in mammalian kidneys.
Where does the loop of Henle originate?
In the kidney, the loop of Henle is the portion of the nephron that leads from the proximal convoluted tubule to the distal convoluted tubule. The loop has a hairpin bend in the renal medulla.

How does the loop of Henle work a level biology?
The role of the loop of Henle is to make an increased salt concentration gradient in the medulla. The loop of Henle is a counter current multiplier; the longer the loop the bigger the concentration gradient in the medulla. This means that more water can be reabsorbed from the descending loop.
How was the loop of Henle discovered?
The loop was discovered by the German physician and anatomist Friedrich Gustav Jacob Henle, also known as Jacob Henle, in the middle of the 19th century [1]. Drastic improvements in light microscopy technology during this time allowed scientists to begin looking closer at cellular structures [2].
Why is the loop of Henle important?
The principal function of the loop of Henle is in the recovery of water and sodium chloride from urine. This function allows production of urine that is far more concentrated than blood, limiting the amount of water needed as intake for survival.
What does the loop of Henle prevent UTI?
Uromodulin (also known as Tamm–Horsfall urinary glycoprotein) is specifically produced in the urinary tract by epithelial cells lining the ascending limb of Henle's loop in kidney nephrons16.
Which structure has the longest loop of Henle?
The longest loop of Henle is found in Kangaroo rats. It is a U-shaped portion of the tubule that conducts urine within each nephron of the kidney.
Which part of the loop of Henle is permeable to water?
The descending portion of the loop of Henle is extremely permeable to water and is less permeable to ions, therefore water is easily reabsorbed here and solutes are not readily reabsorbed.
What are mainly reabsorbed from Henle's loop?
The Henle's loop of nephron is mainly responsible for reabsorption of water in the kidney.
Where is the loop of Henle in the kidney?
Henle's loop dips down from the cortex of the kidney into the deeper tissues of the medulla before looping back up into the cortex. Here, the tubule once again becomes convoluted, forming the distal tubule. The distal tubule ultimately dips back into the medulla, where it connects with a collecting tubule.
What is reabsorbed at the 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.
What does the loop of Henle prevent UTI?
Uromodulin (also known as Tamm–Horsfall urinary glycoprotein) is specifically produced in the urinary tract by epithelial cells lining the ascending limb of Henle's loop in kidney nephrons16.
How is water absorbed in the loop of Henle?
Water is drawn out of the tubule by osmosis due to the high concentration of ions in the surrounding tissue. So, the osmolarity of the urine increases as it descends the LoH. The concentration gradient created by the loop of Henle is maintained by the vasa recta producing a counter-current exchange mechanism.

2. Henle's Loop. Also called the loop of Henle, the Henle’s loop carries both descending limb of loop of henle and ascending limb of loop of Henle. Since the loop of henle location is at the Nephron; both the descending and ascending limbs carry a spongy feeling. The descending limb is the preamble to water but impermeable to the electrolyte ...

· Mammals have even more derived nephrons, which contain an extended loop, called the loop of Henle. Mammals produce urea from ammonia, and concentrate the urea in the urine to a high extent. This promotes the extraction of water from the ultrafiltrate, and allows mammals to live in some of the driest environments on Earth. A camel, for instance ...

Filtrate at the loop of henle has a high concentration of metabolic waste products such as urea, uric acid and creatinine. By the time the filtrate reaches the loop of henle, all the nutrients and substances that the body needs would have already been reabsorbed. 3. Distal Convoluted Tubule. Reabsorption

About 65 per cent of the glomerular filtrate is normally reabsorbed in the proximal convoluted tubule before reaching the loop of Henle. Glucose, amino acids, vitamins, hormones, sodium, potassium, chlorides, phosphates, bicarbonates, much of water and some urea from the filtrate are absorbed. Sulphates and creatinine are not reabsorbed ...

The filtrate flows into the two limbs of the Henle’s loop in the opposite directions and therefore, the flow of blood cells in vasa recta is also in the opposite directions. The concentrated urine is formed in the following ways: NaCl is transported from the ascending limb of the Henle’s loop to the descending limb of the vasa recta.

In chemistry, there are three definitions in common use of the word base, known as Arrhenius bases, Brønsted bases, and Lewis bases.All definitions agree that bases are substances which react with acids as originally proposed by G.-F.
