Question

Explain the formation of urine clearly!!!plzzz fast

Answer 1

Nephron is made up of bowman's capsule, tubule and glomerulus. The renal artery brings impure and oxygenated blood to the glomerulus. The glomerulus filters this blood. During filtration, substances like glucose, amino acids, salts, water & urea present in the blood pass into the bowman's capsule and then enter the tubule of the nephron. The tubule is surrounded by a large no. of cappillaries. The useful substances like glucose, amino acids, water and salts etc are reabsorbed by the tubules which are taken back by the cappilaries. Only the waste substances such as urea, unwanted salts and excess water remain in the tubult. The liquid left behind the tubule of the nephron is urine. The nephron carries this urine in the urine collecting duct in the kidneys from where it is carried to the ureter and then to the urinary bladder.
