Bird. Birds have a four-chambered heart that completely separates O2-rich blood from O2-poor blood. The left ventricle pumps O2-rich blood under pressure to the muscles. Birds are also endothermic. This means that like mammals their internal temperature is constant because they generate and maintain metabolic heat.
