The nephron is the main functional unit of the kidney which is responsible for filtering the blood and concentrating the solution to produce urine.

Diagram of the Nephron, Glomerulus and Different Parts of the Tubule. The tubules are lined with a thin layer of epithelial cells. The thinner segments of the tubules like the descending limb and first part of the ascending limb of the loop of Henle has cells with minimal organelles.

Reabsorption begins in the proximal convoluted tubules and continues in the loop of Henle, distal convoluted tubules, and collecting tubules 3.SECRETION: Secretion is the process by which substances move into the distal and collecting tubules from blood in the capillaries around these tubules.

6.Loop of Henle The Loop of Henle dips down into the hypertonic environment of the kidney medulla and is responsible for the reabsorption of water from the filtrate. Water is drawn out of the descending limb of the loop, by osmosis, into the hypertonic medulla of the kidney.

Kidney Reabsorption. Once inside the lumen of the nephron, small molecules, such as ions, glucose and amino acids, get reabsorbed from the filtrate: 1  Specialized proteins called transporters are located on the membranes of the various cells of the nephron. 2  These transporters grab the small molecules from the filtrate as it flows by them.

This is what happens as the filtrate travels through the nephron. Two major factors affect the reabsorption process: 1  Concentration of small molecules in the filtrate-the higher the concentration, the more molecules can be reabsorbed. 2  Rate of flow of the filtrate-flow rate affects the time available for the transporters to reabsorb molecules.

Processes of the Kidneys. Filtration. Filtration is the mass movement of water and solutes from plasma to the renal tubule that occurs in the renal corpuscle. About 20% of the plasma volume passing through the glomerulus at any given time is filtered.

Reabsorption. Reabsorption is the movement of water and solutes from the tubule back into the plasma. Reabsorption of water and specific solutes occurs to varying degrees over the entire length of the renal tubule. Bulk reabsorption, which is not under hormonal control, occurs largely in the proximal tubule.

2.REABSORPTION: Reabsorption, by definition, is the movement of substances out of the renal tubules back into the blood capillaries located around the tubules (called the peritubular copillaries). Substances reabsorbed are water, glucose and other nutrients, and sodium (Na+) and other ions.

Best Answer: STRUCTURE OF NEPHRON: Nephrons (Greek nephros=kidney) are renal or kidney tubules. Each kidney has over one million nephrons that are responsible for removing waste products from blood and maintaining water, salt and pH balance in the body. This vital job results in the formation of urine.
