The terms actually don't have anything to do with blood except for the fact that blood helps move the heat throughout the body. Cold blooded, or exothermic animals are not able to regulate their internal temperatures. They have to sit in the sun to warm up and sit in the shade to cool off. Warm blooded, or endothermic animals can keep a pretty constant internal temperature. Ours is 98.6 degrees Farenheit. It actually has to do with the part of the brain that controls body regulation, not with the heart.
