n. the space bounded by the bones of the pelvis and containing the pelvic viscera
Wikipedia
The pelvic cavity is a body cavity that is bounded by the bones of the pelvis. Its oblique roof is the pelvic inlet (the superior opening of the pelvis). Its lower boundary is the pelvic floor.
The pelvic cavity primarily contains reproductive organs, the urinary bladder, the pelvic colon, and the rectum. The rectum is placed at the back of the pelvis, in the curve of the sacrum and coccyx; the bladder is in front, behind the pubic symphysis. In the female, the uterus and vagina occupy the interval between these viscera. The pelvic cavity also contains major arteries, veins, muscles, and nerves. These structures have to work together in a little crowded space. They can be affected by many different diseases and by many drugs in many different ways. One part may impact upon another, for example constipation may overload the rectum and compress the urinary bladder, or childbirth might damage the pudendal nerves and later lead to anal weakness.
