Explanation:

First, it ensures complete segregation of oxygenated and deoxygenated blood. Second, blood is received by the upper chambers and is pumped out by the lower chambers. This segregation between received blood and sent blood increases the efficiency of the heart. In four chambered heart left half is completely separated from right half by septa.This prevents oxygenated and deoxygenated blood from mixing This allows a highly efficient supply of oxygenated blood to all parts of the body.This is useful in animals that have high energy needs such as birds and mammals
