The Frog Heart The frog heart has 3 chambers: two atria and a single ventricle. The atrium receives deoxygenated blood from the blood vessels (veins) that drain the various organs of the body. The left atrium receives oxygenated blood from the lungs and skin (which also serves as a gas exchange organ in most amphibians). 1. Introduction. The eyes of frogs and toads (Anura) are among their most striking morphological characteristics.
