Question

What is the advantage of a frog having three chambered heart instead of a four chambered heart?

Answer 1

The four-chambered heart has a distinct advantage over simpler structures: It allows us to send our "dirty" blood to the cleaners-the lungs-and our "clean" blood to the rest of the body without having to mix the two. That system is very efficient.
