What is JuxTamedullary nephron?

nephron is one of the working parts of the kidneys involved in urine production. There are two types of nephrons, known as cortical nephrons and juxtamedular nephrons. The cortical nephron sits in the outer part of the kidneys, known as the bark, while the juxtamedular nephron sits closer to the inner part of the kidney, called Medulla. The part of JuxTamedullary nephron, a letter -shaped tube called Henle loop, is longer than the cortical nephron tube and immerses directly down into the inner medully. This plays an important role in urine formation.

There are many nephrons in the kidneys, probably about a million in total. Each nephron consists of a node of minute blood vessels called glomeruli, enclosed in a capsule, which is associated with a series of tubes. The blood enters the glomerulus and filters into the capsule and then the tube, eventually forms urine. As the filtered blood passes through nephron, it is added to it and the molecule has lost it until the final product is known as urine. Extra long loop Henle found inside each juxtamedullary nefRon allows the kidneys to remove more water from filtered blood, which makes the urine more concentrated.

Every JuxTamedullary nephron has another function that differs from cortical nephron. In addition to each Henle loop, a special extended and U-shaped network of blood vessels leads. These blood vessels are involved in the urine concentration process because they move sodium into the kidney medully. It is important that the inner medulla has a high concentration of particles, such as sodium, because it tends to pull water from the Henle loop, leading to a more concentrated urine.

Henle -shaped loop in each juxtamedular nephron is described as a descending part that immerses down into the kidney and into the ascension of NDING, which rises into tubes that collect urine. Sodium and chloride flow out of the ascending section and are also pumped, causing urine to be slightly diluted. After removal of sodium and chloride increases the concentration of the dissolutionSnked particles in the inner medulle and help pull water out of the loop henle. This concentrates urine. After the urine leaves the ascending part of the Henle loop and enters the collection pipes, they transfer it back to the inner medully, so that even more water is pulled out.
