The uterus is part of a woman's reproductive system that is located in the pelvis between the bladder and the rectum. The uterus is the hollow, pear-shaped organ where a baby grows. The narrow, lower portion of the uterus is called the cervix. The broad, middle part of the uterus is called the body, or the corpus. The dome-shaped top of the uterus is called the fundus. The fallopian tubes extend from either side of the top of the uterus to the ovaries.
Main Functions Of The Fallopian Tubes. The Fallopian tubes, which are also referred to as the uterine tubes, salpinges or oviducts are a pair of 10 cm long and narrow tubes that connect the uterus to the ovary. They are located in the pelvic cavity that extends laterally from the superior edge corners of the uterus, passing superior to the ovaries.
