The chordate classes that have 3-chambered hearts are Amphibia (the amphibians) and Reptilia (the reptiles). Humans and other mammals (birds too) have a four-chambered heart (left atrium, right atrium, left ventricle, right ventricle). Reptiles and amphibians have a left atrium, a right atrium, but only one ventricle (although the ventricle of reptiles has a small internal wall that divides it to some extent).
