This is our attachment point to the uterus and this is our fallopian tube which acts as a passageway to carry that oicide, that ovum from the ovary into the uterus. And if fertilization takes place, we form the zygote. When the sperm cell combines with the ovum and that zygote is implanted onto the wall, onto the lining of the uterus known as the endometrium. So let's focus in on this ovary. Inside the ovary we have these blood vessels, the arteries that carry nutrients and oxygen to the cells of the ovary. And we have the veins, the blue vessels that carry away the waste products and carbon dioxide and ammonium away from the cells of the ovary.
