Why is it necessary to separate oxygenated and deoxygenated blood in mammals and birds?
ScienceClass 10CBSEAnswered 27 Mar 2026
Answer
Solution:
Mammals and birds are warm-blooded animals which keep their body temperature constant irrespective of the environment they live. This process requires a lot of oxygen for more cellular respiration so that warm-blooded animals produce more energy to balance their body temperature. Hence, it is very important for warm-blooded animals to separate oxygenated and deoxygenated blood to keep their circulatory system efficient.
