उत्तर
The process of urine formation takes place in the following steps:
- Glomerular Alteration: Blood containing waste material enters the kidneys through the renal artery. It then enters the glomerulus under high pressure. Water and small solutes are filtered in the Bowman’s capsule.
- Tubular reabsorption: Filterate passes through the thin walls of the Bowman’s capsule into the urinary or renal tubule. As it passes through the tubule, water, and many useful substances are reabsorbed by the renal blood capillaries.
- Tubular secretion: The remaining liquid, along with wastes such as urea, uric acid, etc., is called urine and is collected in the urinary bladder.
- Excretion: Urine leaves the kidneys and passes into the urinary bladder through the ureters. When the urinary bladder is full, urine is passed out through the urethra.
