Urethra (organ): The a urethra is a hollow tube located on the pelvis that connects the bladder to the outside of the body. The urethra's main function is to transport urine that has been collected and stored in the bladder to the outside of the body. In males, the urethra is longer than in females because it runs through the entire length of the penis. In men, it also provides a passageway for the excretion of semen. In females, the urethra opens into the female genitalia area. In the male the urethra opens at the tip of the penis. Together with the bladder, kidneys and ureters, the urethra forms a part of the urinary tract in the genitourinary system.
Conditions that afflict the urethra include urethritis, kidney stones, urethral stricture, hypospadias, epispadias, dysuria, urethral syndrome, and urethral cancer.
Urethra (organ): When you urinate, the brain signals the bladder muscles to tighten, squeezing urine out of the bladder. At the same time, the brain signals the sphincter muscles to relax. As these muscles relax, urine exits the bladder through the urethra. When all the signals occur in the correct order, normal urination occurs.
