Question

How the loop of henlen help to us

Answer 1

Answer:

Loop of henle refers to a portion of the nephron extending from the proximal convulated tubule till the distal convoluted tubule. Its main function is to concentrate urine by selectively absorbing the useful components from it.

This is named as loop of henle because it was discovered by F. G. J. Henle

The wide part of the descending loop of henle is impermeable to ions, water, etc. The narrow part of the descending loop is permeable to water. The water draws out of the filterate by osmosis.

The narow part of the acsending limb is permeable to the inorganic ions and urea. Ions leave the filterate and urea enters the filterate. The wide region of ascending limb pass inorganic ions ut of the filterate.

As a result of this filterate becomes hypotonic to the plasma.

Answer 2

Explanation:

The human kidney is made up of about a million nephrons, the filtering units of this complex and highly vascular organ. Each nephron is composed of a highly coiled tubule, one end of which forms a cup-shaped structure.

Inside this cup and forming a network around its walls, is a tuft of capillaries called a glomerulus, with a special fenestrated basement membrane.

Each glomerulus filters out water and solutes from the blood passing through it into the surrounding space, which is the cavity between the two walls of the cup. This part is wholly within the renal cortex.

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.

Its main function is to reabsorb water and sodium chloride from the filtrate. This conserves water for the organism, producing highly concentrated urine.
