Diagram of the Porcine Female Reproductive Tractsmall uterine body, and the cervix and is of the type of uterus referred to as bicornuate. The two uterine horns are connected and supported by a highly vascularized mesometrium which holds the horns in a convoluted and folded position. Histologically, the uterus consists of an inner layer, the endometrium, a highly glandular and vascularized structure having an epithelial lining of the lumen over a bed of connective tissue. The myometrium is the muscular portion of the uterus, having two layers of smooth muscle, one longitudinal and the other circular. The uterus serves a number of functions, e.g., transport of tozoa to the oviduct, Sperm capacitation in endometrial secretions, production of a luteolytic agent in the event of an infertile mating, nutrient supply to the developing blastocyst in pregnancy and after placentation, direct transfer of nutrients (histotroph) from the endometrial glandular and surface epithelium to the conceptus and finally expulsion of the fetus at term. The functions of the cervix are to present a barrier to bacteria, aid in transport of sperm, and permit expulsion of the fetus. The vagina serves to aid in copulation and as a passageway for fetal delivery.
