Why is it necessary to reduce mixing of oxygenated and deoxygenated blood?
Answer and explanation
Correct answer: So the body receives oxygen more efficiently
The governing concept is efficient transport of oxygen for aerobic respiration. Oxygenated blood carries oxygen from the lungs to body tissues, where cells use it to release energy from food. If it mixes substantially with deoxygenated blood, the oxygen concentration delivered to tissues falls and circulation becomes less efficient. Thus option A is correct. The other choices concern digestion, excretion, or photosynthesis, not blood separation.
