Why do amphibians have 3 chambered hearts?

The heart of an amphibian, such as a frog, has three chambers, one ventricle and two atria. Blood from the ventricle travels to the lungs and skin where it is oxygenated and also to the body. So a heart with three chambers is ideal for the needs of amphibians who could also absorb oxygen through their skin when moist.
