[TFD][VHOG] A tube or collection of tubes in an animal from the ovaries to the outside of the body. AAO:0010533 BSA:0000083 BTO:0000980 EFO:0000974 EMAPA:18984 GAID:366 In all remaining vertebrates (i.e., coelacanths, lungfishes, amphibians, reptiles, birds, and mammals), the oviduct arises in ontogeny as a longitudinal, groovelike invagination of the coelomic epithelium on the lateral surface of the mesonephros.[well established][VHOG] MAT:0000126 MESH:D010057 MIAA:0000126 TAO:0000560 The only female vertebrates to lack oviducts are the jawless fishes. In these species, the single fused ovary releases eggs directly into the body cavity. The fish eventually extrudes the eggs through small genital pores towards the rear of the body[WP] UBERON:0000993 UMLS:C0029954 VHOG:0001136 XAO:0003052 ZFA:0000560 female reproductive tracts in birds divided into infundibulum, magnum, isthmus, uterus, and vagina ovarian duct ovarian tube oviducts sometimes oviduct is used interchangeably with follaopian tube. Here they are different - the oviduct connects the gonad to the outside in a variety of animals. The mammal-class fallopian tube is derived from the mullerian duct and connects the gonads/infubdibulum to the uterus tuba uterina tuba uterinae tubular parts of female reproductive system uberon uterine tube reproductive structure space surrounding organism
