Question

why it is necessary to separate oxygenated and deoxygenated blood ​

Answer 1

It is necessary in higher organisms to seprate oxygenated and deoxygenated blood so that their circulatory system is more efficient and can maintain constant body temperatere and also in order to increase the efficiency of oxygen transport.

Answer 2

$\underline{\sf{Answer:-}}$

${\implies{\sf{}}}$Humans have four chambered heart (which consists of two auricles and two ventricles). The left side and right side of the heart is completely separated to prevent the oxygenated blood from mixing with the deoxygenated blood.

${\implies{\sf{}}}$Such separation is done because it allows a highly efficient supply of Oxygen to the body cells which is necessary for producing a lot of energy.

${\implies{\sf{}}}$This energy is useful in case of human beings that have high energy need because they constantly require energy to maintain their body temperature.
