The Human Male Urinary SystemThe Human Female Urinary SystemThe inside of the bladderHuman male and female urinary bladders and urethras
The urinary bladder is an organ in the humanbody in charge of storing urine. It is part of our urinary system. All the liquids that are drunk go through the bladder. The bladder takes in the liquid in order for the body to work. The bladder works with the kidneys. The kidneys clean the liquid we drink. This goes on until the bladder is too full to hold anymore. At this point, it is roughly the size of a softball. The bladder then tells the brain that it needs to be emptied. Once this message is received by the brain, the muscles around the bladder starts to squeeze and the bladder starts to contract. At the same time, the bladder sends a message to the sphincters to relax and let the liquid pass and pass through the urethra out of the body.
