The mud puppy (Necturus maculosus) has a three-chambered heart, consisting of two atria and one ventricle. The right atrium receives deoxygenated blood from the body, while the left atrium receives oxygenated blood from the lungs. The single ventricle pumps blood to both the lungs and the rest of the body, though some mixing of oxygenated and deoxygenated blood occurs due to the ventricle's structure. This heart design is typical of amphibians, reflecting their aquatic and terrestrial lifestyle.
