As a result, reptiles have a simpler three-chambered heart.

What do reptiles and amphibians have in common?

Amphibians take in oxygen and other gases through their glandular skin and the linings of their mouth and throat (they may also have lungs or gills). Like reptiles, amphibians maintain their body temperature by resting in warm or cold places.
