The arterial system in reptiles has a three-chambered heart similar to amphibians, which directs blood to the lungs and body. The ventricle is more effectively divided by a partial septum compared to amphibians, resulting in less mixing of oxygenated and deoxygenated blood. Reptiles have a heart that directs blood flow to both pulmonary and systemic circuits more efficiently than amphibians.

chambered heart similar to the amphibian heart that
directs blood to the pulmonary and systemic circuits.
