Bladder—A small organ that serves as the reservoir for urine prior to its passing from the body during urination.
Prostate gland—A small gland in the male genitals that contributes to the production of seminal fluid.
Urinary tract—The system of organs that produces and expels urine from the body. This system begins at the kidneys, where the urine is formed; passes through the bladder; and, ends at the urethra, where urine is expelled.
