Amphibians have a three-chambered heart with two atria and one ventricle, which helps to separate some oxygenated and deoxygenated blood. They also have both pulmonary and systemic circuits. Fish have a two-chambered heart and birds have a four-chambered heart. Lungfish are a type of fish with a specialized lung, but they still have a two-chambered heart. Cheetahs are mammals with a four-chambered heart.
