Definition:The spiral valve alternately blocks & unblocks the entrances to the left and right pulmonary arches (sending unoxygenated blood to the skin & lungs).
Comment:[taxon-note] "found in dipnoans and amphibians"; [taxon-note] "The spiral valve is considered to have evolved from the right member of the four embryonic endocardial ridges (Goodrich, 1930 - via Morris 1974)"
Synonyms:xref: AAO:0010251;   http://cwx.prenhall.com/bookbind/pubbooks/martini10/chapter21/medialib/Kardong_fig_12_29.html
