• Glomerulus

The glomerulus is the main filter of the nephron and is located within the Bowman's capsule. A glomerulus and its surrounding Bowman's capsule constitute a renal corpuscle, the basic filtration unit of the kidney. From the Bowman’s Capsule, extends a narrow vessel, called the proximal convoluted tubule. This tubule twists and turns until it drains into a collecting tubule that carries urine toward the renal pelvis.
Glomerulus is a network of extremely thin blood vessels called capillaries. The glomerulus resembles a twisted mass of tiny tubes through which the blood passes. The glomerulus is semipermeable, allowing water and soluble wastes to pass through and be excreted out of the Bowman's capsule as urine. The filtered blood passes out of the glomerulus into the Efferent arteriole to be returned through the medullary plexus to the intralobular vein. 

A large volume of ultrafiltrate is produced by the glomerulus into the capsule. As this liquid traverses the proximal convoluted tubule, most of its water and salts are reabsorbed, some of the solutes completely and others partially. 

A glomerulus is a capillary tuft surrounded by Bowman's capsule in nephrons. It receives its blood supply from an afferent arteriole of the renal circulation. Unlike most other capillary beds, the glomerulus drains into an efferent arteriole rather than a venule. The resistance of the arterioles results in high pressure in the glomerulus aiding the process of ultrafiltration where fluids and soluble materials in the blood are forced out of the capillaries and into Bowman's capsule. The rate at which blood is filtered through all of the glomeruli, and thus the measure of the overall renal function, is the glomerular filtration rate (GFR).

• Henle’s Loop

 Henle’s Loop is part of renal tubule which become extremely narrow that extending down away from Bowman’s capsule and then back up again form a U shape. Surrounding loop of Henle and the other parts of the renal tubule is a network of capillaries, which are formed from a small blood vessel that branches out from glomerulus. 

The liquid entering the loop is the solution of salt, urea, and other substances passed along from glomerulus by proximal convoluted tubule. In this tubule, most of the dissolved components needed by the body; particularly glucose, amino acids, and sodium bicarbonate, is reabsorbed into the blood. The first segment of the loop, the descending limb, is permeable to water, and the liquid reaching the bend of the loop is much richer than the blood plasma in salt and urea. 

As the liquid returns through the ascending limb, sodium chloride diffuses out of the tubule into the surrounding tissue, where its concentration is lower. In the third segment of the loop, the tubule wall can, if necessery, effect further removal of salt, even against the concentration gradient, in an active-transport process requiring the expenditure of energy. In a healty person the reabsorption of salt from the urine exactly maintains the bodily requirement: during periods of low salt intake, none is allowed to escape in the urine, but, in periods of high salt intake, the excess is excreted. 

• Renal Collecting Tubule 

Also called Duct of Bellini, any of the long narrow tubes in the kidney that concentrate and transport urine from the nephrons, to larger ducts that connect with the renal calyces. The liquid from the loop of Henle get into the Distal Convoluted Tubule in which reabsorbtion of sodium continues throughout the whole distal tubule. This reabsorbtion extends to the early part of the Renal Collecting Tubule.
Each collecting tubule is about 20-22 milimetres long and 20-50 microns in diameter. The walls of the tubule are composed of cell with hairlike projection, flagellae, in the tube’s channel. Motions of the flagellae help to move secretion through the tubes. As the collecting tubes become wider in diameter, the cells increase in height so that the wall becomes thicker.
The function of the collecting tubes are transportation of urine and absorbtion of water. It is thought that the tissue of the kidney’s medulla, or inner substance, contains a high concentration of sodium. As the collecting tubule travel through the medulla, the concentration of sodium causes water to be extracted through the tubule walls into the medulla. The water diffuses out between the collecting wall cells until the concentration of sodium is equal in the tubes and outside them. Removal of water from the solution in the tubes serves to concentrate the urine content and conserve body water.
