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.
Why is the loop of Henle a loop?
Loop of Henle, long U-shaped portion of the tubule that conducts urine within each nephron of the kidney of reptiles, birds, and mammals. … This function allows production of urine that is far more concentrated than blood, limiting the amount of water needed as intake for survival.
Who Discovered 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.
What are the two main functions of the loop of Henle?
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 nephron loop also known as?
The loop of Henle (sometimes known as the nephron loop) is a U-shaped tube that consists of a descending limb and ascending limb, which differ in permeability. The collecting duct and distal convoluted tubule are normally impermeable to water, but this is altered due to hormone stimulus during homeostasis.
How does the loop of Henle conserve water?
The loop of Henle is a duct within the renal tubule that helps to conserve water by using counter current exchange.
How does loop of Henle concentrate urine?
Water present in the filtrate in the papillary duct flows through aquaporin channels out of the duct, moving passively down its concentration gradient. This process reabsorbs water and creates a concentrated urine for excretion.
Where is urine formed?
Each nephron consists of a ball formed of small blood capillaries, called a glomerulus, and a small tube called a renal tubule. Urea, together with water and other waste substances, forms the urine as it passes through the nephrons and down the renal tubules of the kidney.

Is the Vasa recta part of the nephron?
|A nephron, the vasa recta are labeled arteriolae rectae|
What is the function of Bowman's capsule?
Bowman’s capsule surrounds the glomerular capillary loops and participates in the filtration of blood from the glomerular capillaries. Bowman’s capsule also has a structural function and creates a urinary space through which filtrate can enter the nephron and pass to the proximal convoluted tubule.
What occurs in glomerulus?
glomerulus: A small, intertwined group of capillaries within nephrons of the kidney that filter the blood to make urine. hydrostatic pressure: The pushing force exerted by the pressure in a blood vessel. It is the primary force that drives glomerular filtration.
Which part of the human body is Bowman's capsule found?
The Bowman’s capsule is found in the outer part of the kidney, the cortex. Essentially, the capsule is a sealed, expanded sac at the end of the tubule, the rest of which elongates into a twisted and looped tubule in which urine is formed. Figure 9.2. Structural overview of a nephron, the functional unit of the kidney.
How long is a nephron?
Each nephron in the mammalian kidney is a long tubule, or extremely fine tube, about 30–55 mm (1.2–2.2 inches) long. At one end this tube is closed, expanded, and folded into a double-walled cuplike structure.
What are the two types of nephron?
There are two basic kinds of nephrons: cortical nephrons and juxtamedullary nephrons. These distinctions have to do with the location of the glomerulus, the tiny ball of capillary network, and the penetration into the medulla by the loops of the nephron tubule.
