And now the secondary ocyte, which by the way, is still in metaphase II of meiosis, will begin to travel along our philopium two. Now, notice that the remaining cells that came from the secondary follicle remain in our ovary. And the remaining portion of that secondary follicle will eventually develop into a structure known as the corpus luteum. And the corpus luteum is essentially an endocrine gland that continues to release different types of hormones that are responsible for maintaining the thickening, the thick layer of that endometrium inside the uterus. And this is in the case that when the sperm cell fuses with the XL, we form the zygote and the zygote eventually implants onto the uterus. Now, if there is a sperm cell found inside our philopium tube, it basically combines it fuses with our secondary OSI.
