Quizplus · Accepted Answer

The secondary oocyte is released from the ovary into the peritoneal cavity and travels through the uterine tube to travel to the uterus. If it is not fertilized in the uterine tube, it would be expelled along with the endometrium during menstruation. The myometrium is the smooth muscle layer that is never part of the menstrual flow. The primary oocyte is developing in the ovary before ovulation and the zygote is formed after the sperm fertilizes the secondary oocyte.
