why is double circulation essential in high energy needed animals like human?
Answers
Answer:
The majority of mammals (including humans) utilize a double circulatory system. ... Double circulatory systems are important because they ensure that we are giving our tissues and muscles blood full of oxygen, instead of a mixture of oxygenated and deoxygenated blood.

Answer:
Warm-blooded animals such as birds and mammals maintain 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 necessary for them to separate oxygenated and deoxygenated blood, so that their circulatory system is more efficient and can maintain their constant body temperature
