The excretory system in human beings includes a pair of kidneys a pair of ureters a urinary bladder and urethra.



Kidneys are located in the abdomen one on either side of backbone .


Urine produced in the kidneys passes through the ureters into the urinary bladder where it is stored until it released through the urethra.



The purpose of making urine is to filter out waste products from the blood in the lungs nitrogenous waste such as urea or uric acid are removed from blood in the kidneys


kidney is associated with a cup shaped end of a tube that collect the filtered urine


Each kidney has large number of these filtration called nephrons packed closed together



The urine forming in each kidneys eventually enters a long tube the ureter which connect kidneys with a urinary bladder .


Urine is stored in urinary bladder until the pressure of the expanded bladder leads to the urge to pass it out through the urethra
