It lacks chambers and endocardium.... The innovation of the chambered heart was a key event in vertebrate evolution, because the chambered heart generates one-way blood flow with high pressure, a critical requirement for the efficient blood supply of large-body vertebrates... all extant vertebrates have hearts with two or more chambers (Moorman and Christoffels 2003)\" DOI:10.1101/gad.1485706" . <http://purl.obolibrary.org/obo/UBERON_0000948> <http://www.w3.org/2004/02/skos/core#notation> "UBERON:0000948" . <http://purl.obolibrary.org/obo/UBERON_0000948> <http://purl.obolibrary.org/obo/IAO_0000115> "A myogenic muscular circulatory organ found in the vertebrate cardiovascular system composed of chambers of cardiac muscle.
