Explain the structure of nephron.

Explanation

Each kidney consists of more than one million nephrons. Nephrons or uriniferous tubules are structural and functional units of the kidneys. Each nephron consists of Renal corpuscle or Malphigian corpuscle and renal tubule. The renal corpuscle consists of a cup-shaped structure called Bowman.s capsule containing a bunch of capillaries called glomerulus. Blood enters the glomerular capillaries through afferent arterioles and leaves out through efferent arterioles and leaves out through efferent arterioles. The Bowman.s capsule continues as the renal tubule which consists of three regions proximal convoluted tubule, U-shaped hair pin loop, of Henle and the distal convoluted tubule. The distal convoluted tubule which which opens into the collecting tubule. The nitrogenous wastes are drained into renal pelvis which leads to ureters and stored in the urinary bladder. Urine is expelled out through the urethra.
