NCERT · Class 10 · Science · Life ProcessesWhy is the separation of oxygenated and deoxygenated blood necessary in mammals and birds?
Step-by-Step Solution
The complete physical and physiological separation of oxygenated and deoxygenated blood is extremely necessary in warm-blooded animals such as mammals and birds because they have a constant and high metabolic energy requirement to maintain their internal body temperature irrespective of the surrounding environmental temperature. Efficient separation ensures that the body tissues receive a maximum supply of oxygenated blood at all times, which is thoroughly utilized to yield high amounts of energy through cellular respiration. This high-efficiency system supports their active lifestyles, high body temperature maintenance, and high energy demands effectively.
