II. Gravid Uterus: The uterus enlarges 20 times: 1. Stretching of supporting ligaments & muscles. 2. Pressure on intra-abdominal structures & ant abd wall, prevents irritation of ant abd wall by inflamed intra-abdominal organs → decreased perception of somatic pain & localization 3. Obstructs & inhibits the movement of the omentum (policeman of the abdomen): prevents omentum from localizing infection
