प्रश्न
Answer the following in detail.
Explain the structure of a nephron with the help of a diagram.
उत्तर
The microscopic filtering unit of the kidney is called nephron or uriniferous tubule. Each nephron consists of a cup-shaped structure at one end called Bowman’s capsule. Inside the cup is a network of blood capillaries called a glomerulus. The Bowman’s capsule and the glomerulus together form the Malpighian body. The Bowman’s capsule extends into a long tubule. These tubules are surrounded by a network of renal capillaries. The urinary tubules of the nephrons in each kidney join to form a common tube called a ureter.
