To better understand pelvic inflammatory disease, it helps to understand the anatomy of the uterus, cervix, and Fallopian tubes.

The uterus, or womb, is part of the female reproductive system. The cervix is the lowest part of the uterus. The ovaries, fallopian tubes and vagina are the other parts of the female reproductive system.

Anatomy examples:

• The uterus, cervix, and vaginal canal
• The bladder
• The fallopian tubes:
• These paired structures connect each ovary to the uterus
• The ovaries:
• One on each side of the uterus. A normal adult ovary is about the size of an unshelled almond
• Female organs during a pelvic examination
