प्रश्न
Why is the double circulation of blood in human beings necessary?
उत्तर
It is necessary for human beings to separate oxygenated and deoxygenated blood because this makes their circulatory system more efficient and helps in maintaining a constant body temperature. The energy demands for human beings are very high and hence the separation of oxygenated and deoxygenated blood is necessary to meet this energy demand.
