Oxygenated and deoxygenated bloods are separate in the heart of mammals. Give Reasons.

• The circulatory system in mammals has a double circulation system where the oxygenated, as well as deoxygenated blood, remains separated. 
• This is essential so as to maintain the body temperature efficiently over a wide range. 
• Mammals require a higher supply of oxygen for more cellular respiration so that they can produce more energy to maintain their body temperature.
• It is also better if the oxygenated blood stays separate, as its combination with deoxygenated blood will impure the entire blood.
