Question

What is the advantage of the four chambered heart of mammals over the three chambered heart?

Answer 1

The four-chambered heart has a advantage like: 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.

The heart has different chambers to prevent the mixing of Oxygenated and De-oxygenated blood. So it allows a highly efficient supply for oxygen to the body. It also helped to maintain the body temperature.
