The uterus is a hollow organ, and the cavity is covered with a layer of mucosa, which is called uterine mucosa.

The uterus is located in the female pelvic cavity. Under normal circumstances, the uterus and * * * have a self-defense system and will not be easily invaded by bacteria. When pelvic inflammatory disease is caused by various reasons, women will have symptoms such as abdominal distension, pain and lumbosacral pain before and after menstruation. Abdominal distension, pain and drooping are often obvious before and after menstruation.
