The oviduct may be divided into the infundibulum, magnum, isthmus, uterus and vagina.  The oviduct not only conducts the fertilized ovum to the [[The_Avian_Vent_and_Cloaca_-_Anatomy_%26_Physiology#The_Cloaca|Cloaca]], but adds substantial amounts of nutrients.  It also encloses the ovum within membranes and a shell, providing protection for the embryo.  It conveys spermatozoa to the ovum for immediate fertilization and stores them for future use.  One insemination is sufficient to fertilize the ova released during the following 10 days.
