A four chambered heart is a closed system and ensures that all blood passing through it is oxygenated. A three chambered heart has both oxygenated an non-oxygenated blood mixed in the single ventricle therefore the blood is only half oxygenated. A three chambered creature would suffer from exhaustion long before a four chambered creature.
