Course : Anatomy of the reproductive organs of animals Sexual organs are made up of individuals paired gonads , sexual pathways of the paranasal gonads and unpaired organs of copulation . In the gonads - the testes in males and ovaries in females - develop appropriate reproductive cells : sperm in males and eggs in females . Testes are testicular sac , ovaries, - in the abdominal cavity. The males through sexual pathways are derived sperm from the genital glands. These ways include: testicular network , testicular appendages , seed tubes and urinary canal. The females pathways consist of jajtceprovodov , uterus , vagina and urinary vestibule . Jajtceprovodov send a fertilized egg from the ovary to the uterus , in which the ripening of the fruit, and at the end of this process comes the act of giving birth - the expulsion of the fetus from the uterus matured into the environment through the vagina and urinary threshold . Subordinate more developed gonads in males . To them the dog is only one cancer: prostate , highlight it with sperm cells form sperm. In the female sex glands, paranasal minor vestibular glands , and as laid down in the wall of the urinary vestibule . The organs of copulation in the male penis is , with his sperm injected into bodies of mating females , the latter consist of external genitalia, urinary and vaginal vestibule . From this work it is clear that the device maintains the breeding species and an increase in population size. If you get more information, visit our site: BEST ESSAY CHEAP
