So this diagram basically describes the process by which our follicles mature into our ovum, into our excel. So we begin with these tiny little dots known as the primary follicles. They mature into the oocide, then they become the secondary follicle. 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.
