give reasons oxygenated and deoxygenated blood are separated in the heart of mammals second part ventricles are thick walled SIP third part herbivores have longer small intestine in as compared to carnivorous
Answers
Answer:
It is necessary in mammals and birds to separate oxygenated and de-oxygenated blood because this makes their circulatory system is more efficient and helps in maintaining constant body temperature.
Answer:
1. In birds and mammals have a double circulation system where both the oxygenated and deoxygenated blood maintains separate.
2. Warm-blooded animals such as birds and mammals maintain constant body temperature by cooling themselves when they are in a hotter environment and warming their bodies when they are in a cooler environment.
3.Hence, these animals require more oxygen (O2) for more cellular respiration to produce more energy to maintain their body temperature.
4.They must separate oxygenated and de-oxygenated blood so that their circulatory system is more efficient and can maintain their constant body temperature.
5.It is also better if the oxygenated blood stays separate, as its combination with deoxygenated blood will impure the entire blood.
