Frogs have three-chambered hearts, consisting of two atria and one ventricle. Tadpoles, on the other hand, have a two-chambered heart with one atrium and one ventricle. As tadpoles undergo metamorphosis into frogs, their hearts change structure to support the shift from aquatic to terrestrial life.

A tadpole has gills when they are little, and adult frogs have lungs. The lungs develop as they get older.
