Final answer:
The uterus is a pear-shaped muscular organ located in the pelvis. It has three sections: the fundus, the body, and the cervix. The cervix produces mucus secretions that help sperm move through the reproductive tract.
Step-by-step explanation:
The uterus is a pear-shaped muscular organ that is located above the vagina and behind the bladder in the center of the pelvis. It has three sections: the fundus, which is the superior portion above the opening of the uterine tubes; the body of the uterus, which is the middle section; and the cervix, which is the narrow inferior portion that projects into the vagina. The cervix produces mucus secretions that can facilitate sperm movement through the reproductive tract.
