Mammals need more energy to maintain their body temperature that's why they have. four chambered
heart. In the mammal heart, the oxygenated and deoxygenated blood is not allowed to mix, and this is achieved by the separation of the heart into right side and left side. Such a separation of heart provides an efficient method of supplying oxygen to the body. Fish have two chambered heart and oxygenation of blood takes place in the gills and
passes directly to the rest of the body.
