Urine

Urine is the liquid waste substance excreted by the body. It is produced by the kidneys, sent to the bladder via the ureters, and then excreted by the body down the urethra. Various urinary symptoms include excessive urine, urine retention, urination pain, and so on. Various urinary system disorders can occur including kidney disorders, bladder disorders, urinary tract infection, and other urinary disorders.

Your kidneys make urine by filtering wastes and extra water from your blood. The waste is called urea. Your blood carries it to the kidneys. From the kidneys, urine travels down two thin tubes called ureters to the bladder. The bladder stores urine until you are ready to urinate. It swells into a round shape when it is full and gets smaller when empty. If your urinary system is healthy, your bladder can hold up to 16 ounces (2 cups) of urine comfortably for 2 to 5 hours.
