3. Infundibulum is the funnel-shaped oviduct tip / enlarged and adjacent to the fimbriae. Functioning accommodate ovum that has been captured by the fimbriae.
4. The fallopian tubes are elongated channel after the infundibulum which served as the site of fertilization and the way for the ovum to the uterus with the aid of cilia on the walls.
5. Oviduct is a long line continuation of the fallopian tubes. Function as the site of fertilization and the way for ovum towards the uterus with the aid of cilia on the walls.
6. The uterus is a hollow, muscular organ. Shaped like a pear with a smaller bottom. Functioning as a place of embryo growth. Type the uterus in humans is a simplex with one room for only one fetus. The uterus has 3 kinds of wall layers, namely:
