Hey!!! Here's Ur Answer
➡The waste which is present in the blood has to be removed from the body. A system to filter the is required. This is done by the blood capillaries in the kidneys. When blood reaches the two kidneys, it contains both useful and harmful substances.
The useful substances are absorbed back into the blood after filtration in kidneys. The waste dissolved in water are removed as urine. From the kidneys the urine goes into urinary bladder through tubes called ureters.
It is stored in the bladder and is passed out through the muscular tube called urethra. The kidneys, ureters, urinary bladder and urethra form the excretory system.

The urinary system, also known as the renal system, produces, stores and eliminates urine, the fluid waste excreted by the kidneys. The kidneys make urine by filtering wastes and extra water from blood. Urine travels from the kidneys through two thin tubes called ureters and fills the bladder
