Detailed explanation-1: -The urogenital system has two major subdivisions, the urinary tract and the genital tract. The urinary tract, consisting of the kidneys, ureters, urinary bladder, and urethra, is responsible for the production, storage, and elimination of urine.
Detailed explanation-2: -2.1 Embryology The genital tract is derived from the urogenital ridge, where the testes develop in the dorsal wall of the abdominal cavity. They descend into the scrotum with an evagination of the peritoneum, the tunica vaginalis propria, which forms a serous cavity around the testes.
Detailed explanation-3: -The formation of the metanephros gives rise to the permanent kidney in humans, as well as in other mammals, reptiles, and birds. The development of the metanephros is initiated by the outgrowth of the ureteric bud (UB) from the caudal end of the WD at 4 to 5 weeks’ gestation.
