The wall of the uterine tube consists of the following three layers: The serosa, a serous membrane, lines the outside of the uterine tube. The middle muscularis consists of two layers of smooth muscle that  generate peristaltic contractions that help propel the oocyte forward. The inner mucosa consists of ciliated columnar epithelial cells that help  propel the oocyte forward, and secretory cells that lubricate the tube and  nourish the oocyte. The uterus (womb) is a hollow organ within which fetal development occurs. The  uterus is characterized by the following regions: The fundus is the upper region where the uterine ducts join the uterus. The body is the major, central portion of the uterus.

The inside of the cervix, or cervical canal, opens to the uterus above through the internal os and to the vagina below through the external os. Cervical mucus secreted by the mucosa layer of the cervical canal serves to protect against bacteria entering the uterus from the vagina. If an oocyte is available for fertilization, the mucus becomes thin and slightly alkaline. These are attributes that promote the passage of sperm. At other times, the mucus is viscous and impedes the passage of sperm....
