Question

Answer

Loop of Henle. The Loop of Henle (LoH) is a long, straight, tubular segment connecting the proximal tubule to the distal convoluted tubule and lies parallel to the collecting ducts. The LoH descends from the cortex or medulla (depending on the size/length of the nephron) into the papilla of the kidney.

Answer

Henle's loop is located in the 'medulla of the kidney'
which is after the cortex of the kidney

Answer

It is explained well in ncert

Answer

Location of Henle's Loop
Henle's loop, an essential structure of the nephron, is primarily located in the medulla of the kidney. Understanding its position and function is crucial for grasping renal physiology.
Structure and Function
- Nephron Anatomy: The nephron is the functional unit of the kidney, consisting of various segments, including the proximal tubule, Henle's loop, distal tubule, and collecting duct.
- Loop of Henle: Henle's loop has a descending and an ascending limb. It plays a pivotal role in the concentration of urine by creating a concentration gradient in the medulla.
Importance of the Medulla
- Medullary Role: The medulla is the innermost part of the kidney, where the loops of Henle are situated. This region is essential for urine concentration due to its unique countercurrent multiplication mechanism.
- Osmotic Gradient: The loop of Henle establishes an osmotic gradient, which is crucial for the reabsorption of water and electrolytes. This process allows the kidneys to produce concentrated urine, conserving water in the body.
Comparison with Other Regions
- Cortex: The cortex contains the renal corpuscles and proximal convoluted tubules but does not house Henle's loop.
- Pelvis: The renal pelvis is the funnel-shaped structure collecting urine from the kidney before it enters the ureter. It does not contain nephrons.
- Renal Columns: These structures separate the renal pyramids and also do not contain Henle's loop.
In summary, Henle's loop is located in the medulla, where it plays a critical role in the kidney's ability to concentrate urine and maintain water balance.
