The infundibulum is an accessory sex organ.  It has embryological origins from the Mullerian duct.  It is part of the uterine tube (fallopian tube, or oviduct) and is shaped somewhat like a funnel.  It is lined with cilia that produce a current that usually sweeps the ovum into the uterine tube.  Dr. J particularly likes the following analogy.  The infundibulum is similar to the hood of a raincoat.  It covers the ovary just as the hood covers one's head.  Another analogy he uses is a catcher's mit and a baseball.  The two objects are not sealed together.  On the deep side of the infundibulum we find the oviduct.
