Why is it necessary to separate oxygenated and de-oxygenated blood in mammals and birds? |
|
Answer» Birds and mammals have a double circulation system. 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 de- oxygenated blood will impure the entire blood. Bird and animals have complex body structures . Mammals for performing work and birds for flying require large amount of energy which they get from the breakdown of glucose with oxygen . If there is no seperation between the oxygenated and deoxygenated blood then the requirement of energy wouldn't be fulfilled . Also bodies of mammals and birds gets heat up very quickly , to maintain the temperature it becomes necessary to separate oxygenared and deoxygenated blood in the circulatory system. Hence birds and mammals have double circulatory system that helps them to do so . |
