The uterus is part of a woman's reproductive system that is located in the pelvis between the bladder and the rectum. The uterus is the hollow, pear-shaped organ where a baby grows. The narrow, lower portion of the uterus is called the cervix. The broad, middle part of the uterus is called the body, or the corpus. The dome-shaped top of the uterus is called the fundus. The fallopian tubes extend from either side of the top of the uterus to the ovaries.
The uterus has three parts: 1  Top: The top (fundus) of your uterus is shaped like a dome. 2  From the top of your uterus, the fallopian tubes extend to the ovaries. 3  Middle: The middle part of your uterus is the body (corpus). 4  This is where a baby grows. 5  Bottom: The narrow, lower part of your uterus is the cervix.
