Question

In mammals and birds why is it necessary to separate oxygenated and deoxygenated blood?

Answer 1

Hint: These animals need more oxygen for more cellular respiration so that they can generate more energy to keep their body temperature. It is also important that the oxygenated blood stays separate, as its combination with deoxygenated blood will impure the entire blood.

Complete Answer:
1) The circulatory system in mammals consists of pulmonary circulation and systemic circulation. The pulmonary circulation consists of the pulmonary arteries and the pulmonary veins.
2) The small, broad vessel branches into the pulmonary arteries that deliver blood low in oxygen to the lungs. Blood first passes via the pulmonary valve then again it is released into the pulmonary arteries.
3) Warm blooded animals have a double circulation system where both the oxygenated and deoxygenated blood is separately maintained.
4) Warm-blooded animals like birds and mammals keep consistent body temperature by cooling their body when they are in a high temperature environment and by warming themselves when they are in a cold environment.
5) It is important for them to separate oxygenated and deoxygenated blood in order that their circulatory system is more effective and can keep their constant body temperature.

Note: Animals, birds and mammals have the feature that they can generate body heat, even if it is cold in the outer environment. It is important that the oxygenated and deoxygenated blood is separated in order that the body no longer produces excessive heat because of excessive production of carbon dioxide.
