Inflammation of a fallopian tube (the tube that goes from the ovary to the top of the uterus): "Salpingitis is usually caused by an infection which spreads upward from the vagina (muscular passage which forms part of the female reproductive system), cervix (the neck and outlet of the uterus), and the uterus (the hollow, muscular organ of the female reproductive system in which the fertilized ovum [egg] normally becomes embedded and in which the developing embryo [unborn child during the first eight weeks of development] and the fetus [the unborn child from the end of the eighth week after fertilization until birth] is nourished and grows)."
