(b) : Each Fallopian tube is about $10-­12\ cm$ long and extends from the periphery of each ovary to the uterus, the part closer to the ovary is the funnel­shaped infundibulum. The edges of the infundibulum possess finger­like projections called fimbriae, which help in collection of the ovum after ovulation. The infundibulum leads to a wider part of the oviduct called ampulla. The last part of the oviduct, isthmus has a narrow lumen and it joins the uterus.
