Function of nephron class 10

What are • The nephron has a cup-like capsule called Bowman’s capsule at its upper end and the lower end is a tube-like structure called tubule. • The Bowman’s capsule and the tubule taken together constitute a nephron. • Blood at high pressure flows into these tubules by blood capillaries called glomerulus, which are surrounded by Bowman’s capsule. • This cup-shaped structure is followed by a long tubular structure, which is convoluted and twisted. 9 Important Functions Of Nephrons • Nephrons helps the body to get rid of the unwanted components. • Nephrons also control the blood volume, pressure of blood. As blood pressure gives way to a number of complications, it is important to regulate it. • It regulates the level of metabolites and electrolytes • The useful substances like glucose, amino acids, salts and a major amount of water are selectively reabsorbed by the tubular part of nephron.. • Nephron also helps in the maintenance of blood pH. • • It also ensures to remove only harmful substances from the body that includes nitrogenous materials. • Some substances like K* are actively secreted into the urine through the tubule. • The collecting duct collects the urine and passes it to the ureter.

Structure of nephron A nephron is a microscopic structural and functional unit of the kidney. It is made of a renal corpuscle and a renal tubule. The renal corpuscle consists of a network of capillaries called glomerulus and Bowman's capsule. The corpuscle and tubule both are connected. They are made of epithelial cells. The tubule has five parts, namely: 1. Proximal convoluted tubule which is connected to the Bowman's capsule. 2. The loop of Henle which has two parts, ascending loop of Henle and descending loop of Henle. 3. Distal convoluted tubule 4. The collecting tubule 5. Collecting ducts Functions of nephron. Filtration of blood takes place in the Bowman's capsule. Blood reaches the glomerulus through afferent arteriole of the renal artery. The amount of blood that enters the Bowman's capsule while passing through glomerulus is called filtrate. The filtrate contains glucose, amino acid, salts, and water. This filtrate passes through renal tubule where selective reabsorption takes place. The useful substances like glucose, amino acid, water etc are reabsorbed. The remaining filtrate is called urine which is collected in the collecting duct. Nephron Structure A nephron is a microscopic structural and functional unit of the kidney.
