Amphibians and most reptiles possess a three-chambered heart, which consists of two atria and one ventricle. This heart structure allows for some mixing of oxygenated and deoxygenated blood, which is less efficient than the four-chambered heart found in birds and mammals. Some reptiles, like crocodilians, have a more advanced heart with a partial separation of the ventricle, but the typical three-chambered heart is characteristic of amphibians and most other reptiles.
