And that secondary follicle eventually undergoes the process of ovulation. This is the release of the secondary follicle. It's the release of the mature ovum, the mature excel, into the cavity known as the parrotmeal cavity. And then once released into our parrotmeal cavity, it travels into our fallopium tube and eventually into our uterus. Now the remaining portion of our secondary follicle, the remaining portion of the ovarian follicle, which is the basic unit of structure of our ovary, this remaining portion that is left behind in the ovary eventually becomes a structure known as the corpus luteum. And this is a very important structure in both our menstrual cycle as well as pregnancy.
