Question

In mammals and birds why it is necessary to seprate oxygenated and de-oxugenayed blood​

Answer 1

Answer:

In birds and mammals have a double circulation system where both the oxygenated and deoxygenated blood maintains separate.

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 (O2) for more cellular respiration so that they can produce more energy to maintain their body temperature.

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.

It is also better if the oxygenated blood stays separate, as its combination with deoxygenated blood will impure the entire blood.

In mammals and birds it is necessary to separate oxygenated and de-oxygenated blood so that their circulatory system is more efficient and can maintain their constant body temperature.
