Gravid uterus, illustration. The gravid or pregnant uterus at this late stage of pregnancy fills the pelvic and abdominal cavities. Peripheral and lateral to the uterus are the ovaries and fallopian tubes, with segments of small bowel seen along its upper margins. The colon forms an arch-like structure around the uterus.
