Explain the structure of a nephron with the help of a diagram.

A nephron is the functional unit of a kidney. Each nephron consists of a cup-shaped structure at one end called the Bowman's capsule. It extends into a long urinary tubule that is surrounded by a network of renal capillaries. The urinary tubules of nephrons in each kidney join to form a common tube called the ureter. Inside the Bowman’s capsule, is a network of blood capillaries called glomerulus. The Bowman’s capsule and glomerulus together form the Malpighian body.
