Question

Why does birds have 4chambers of heart

Answer 1

Flight muscles need a lot of oxygen and to get it the blood must keep moving rapidly around the system. To achieve this birds have evolved a four chambered heart

Answer 2

➡Birds and mammals are warm blooded animals and maintain a constant body temperature by cooling themselves when they are in a hotter environment and by warming their bodies when they are in a cooler environment. Hence, these animals require more oxygen for more cellular respiration so that they can produce more energy to maintain their body temperature. Thus, it is important to have a four chambered heart to separate oxygenated and de-oxygenated so that their circulatory system is more efficient and can maintain their constant temperature.⬅
