So the fallopian tube basically connects our ovary to the uterus. Now eventually the ovum will make its way to our uterus, which is this section here. And if we have the presence of sperm cells inside the female reproductive system, then the sperm cell can combine with our ovum in a process known as fertilization and that produces our diploid cell, the zygote. And once the zygote is inside the uterus, it implants onto, it attaches onto the outer membrane the lining of the uterus known as the endometrium. And what the endometrium does is it supplies the developing zygote with the nutrients that it needs to actually develop further. Now, if there is no sperm cells found in our female reproductive system, then when the exile actually reaches our uterus, what happens is the exile, the ovum, along with the lining of the uterus, the endometrium is released into the surrounding environment.
