A dorsiventral (Lat. dorsum, "the back", venter, "the belly") organ is one that has two surfaces differing from each other in appearance and structure, as an ordinary leaf.[1] This term has also been used as a synonym for dorsoventral organs, those that extend from a dorsal to a ventral surface.[citation needed] This word is also used to define body structure of an organism, e.g. flatworm have dorsiventrally flattened bodies.[2]
