Explanation:
The urinary system, also known as the renal system or urinary tract, consists of the kidneys, ureters, bladder, and the urethra. The purpose of the urinary system is to eliminate waste from the body, regulate blood volume and blood pressure, control levels of electrolytes and metabolites, and regulate blood pH. The urinary tract is the body's drainage system for the eventual removal of urine.[1] The kidneys have an extensive blood supply via the renal arteries which leave the kidneys via the renal vein. Each kidney consists of functional units called nephrons. Following filtration of blood and further processing, wastes (in the form of urine) exit the kidney via the ureters, tubes made of smooth muscle fibres that propel urine towards the urinary bladder, where it is stored and subsequently expelled from the body by urination (voiding). The female and male urinary system are very similar, differing only in the length of the urethra.[2]

Urinary system in the male. Urine flows from the kidneys via the ureters into the bladder where it is stored. When urinating, urine flows through the urethra (longer in males, shorter in females) to exit the body

Urine is formed in the kidneys through a filtration of blood. The urine is then passed through the ureters to the bladder, where it is stored. During urination, the urine is passed from the bladder through the urethra to the outside of the body.
800–2,000 milliliters (mL) of urine are normally produced every day in a healthy human. This amount varies according to fluid intake and kidney function
Answer:
Here, is simple and easy answer.
Point wise-
Explanation:
The purpose of making urine is to filter out waste products from the blood.Just as Co2 is removed from the blood in the lungs, nitrogenous waste such as urea and uric acid are removed from blood in the kidneys.
*The basic filtration unit is kidneys.
*Each capillary cluster in the kidney is associated with the cup shaped end of a tube that collects the filtration urine.
*Each kidney has large no.of filtration units called nephrons packed close together.
*Some substance in the initial filtration, such as glucose, amino acids,water, salts etc.are selectively re-absorbed as the urine flows along the tube.
* The amount of re absorbed depends on how much of excess water there is in the body to excreted.
*Each kidney enters a long tube , the ureter, which connects the kidney with the 7rinary bladder.
*Urine is stored in the urinary bladder until the pressure of the expanded bladder leads to the urge to pass it out through the urether.
