Detailed explanation-3: -There is also a structural advantage to having the lungs be separate, the main one being that the bronchial tubes bifurcate naturally, and that there is a place for the heart and other “indivisible” organs in the middle. Separation also decreases the chance of problems or disease in one spreading to the other.
