The uterus has three parts:
- Top: The top (fundus) of your uterus is shaped like a dome. From the top of your uterus, the fallopian tubes extend to the ovaries.
- Middle: The middle part of your uterus is the body (corpus). This is where a baby grows.
- Bottom: The narrow, lower part of your uterus is the cervix. The cervix is a passageway to the vagina.
The wall of the uterus has two layers of tissue:
- Inner layer: The inner layer (lining) of the uterus is the endometrium. In women of childbearing age, the lining grows and thickens each month to prepare for pregnancy. If a woman does not become pregnant, the thick, bloody lining flows out of the body. This flow is a menstrual period.
- Outer layer: The outer layer of muscle tissue is the myometrium.
