Question 2:
Why is it necessary to separate oxygenated and deoxygenated blood in mammals and
birds?
Answer
Warm-blooded animals such as birds and mammals 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 (O2) 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 de-oxygenated blood, so that their circulatory
system is more efficient and can maintain their constant body temperature.
