In many species with two uteruses, only one is functional. Humans and other higher primates such as chimpanzees, along with horses, usually have a single completely fused uterus, although in some individuals the uteruses may not have completely fused [Wikipedia:Uterus] uterus GAID:172 uterine CALOHA:TS-1102 UMLS:C0042149 FMA:17558 Most animals that lay eggs, such as birds and reptiles, have an oviduct instead of a uterus. In monotremes, mammals which lay eggs and include the platypus, either the term uterus or oviduct is used to describe the same organ, but the egg does not develop a placenta within the mother and thus does not receive further nourishment after formation and fertilization. Marsupials have two uteruses, each of which connect to a lateral vagina and which both use a third, middle 'vagina' which functions as the birth canal. Marsupial embryos form a choriovitelline 'placenta' (which can be thought of as something between a monotreme egg and a 'true' placenta), in which the egg's yolk sac supplies a large part of the embryo's nutrition but also attaches to the uterine wall and takes nutrients from the mother's bloodstream. internal genitalia internal genitalia subdivision of oviduct body proper
