Reptiles have a more complex heart than amphibians. Here's a brief comparison:
Amphibians (like frogs and toads):
- Have a three-chambered heart: two atria and one ventricle
- Oxygenated and deoxygenated blood mix in the ventricle
- Less efficient oxygen delivery to body tissues
Reptiles (like snakes, lizards, and crocodiles):
- Have a three- or four-chambered heart (depending on the species)
- Three-chambered heart: two atria and one ventricle (similar to amphibians)
- Four-chambered heart
