Describe the structure and functioning of nephron in the human body

Describe the structure and functioning of nephron in the human body. (Ans) Nephrons are the filtration units of kidney. Each kidney has a large no. of nephrons. The process starts with filteration of urine.

Cup-shaped structure associated with capillaries is called Bowmans capsule. This collects filtered urine. As this urine flows through the tubular part of nephron, reabsorption of glucose, amino acids, salts and water take place. The amount of water and other substances reabsorbed depends upon how in excess they are present in the body.The urine formed enters into a long tube called ureter through the collecting ducts of kidney. Then urine is collected in urinary bladder.
