The Urogenital System

This system (Apparatus urogenitalis) includes two groups of organs, the urinary and the genital. The urinary organs elaborate and remove the chief excretory fluid, the urine. The genital organs serve for the formation, development, and expulsion of the products of the reproductive glands. In the higher vertebrates the two apparatus are independent except at the terminal part, which constitutes a urogenital tract, and includes the vulva in the female and the greater part of the urethra in the male.
