Use the following information to answer the question(s) below
Due to its system of air sacs connected to the lungs, the respiratory system of birds is arguably the most effective respiratory system of all air-breathers. Upon inhalation, air first flows into posterior air sacs, then into the lungs, and then into anterior air sacs on the way to being exhaled. Thus, there is one-way flow of air through the lungs, along thousands of tubules called parabronchi. If the inner lining of the air sacs is neither thin nor highly vascularized, then what can be inferred about the air sacs? A) They must not belong to the respiratory system. B) They cannot be derived from endoderm. C) They are not efficient sites of gas exchange between air and blood. D) They must obtain nutrition from some source other than the bloodstream. E) They cannot effectively moisturize the air before it reaches the lungs.
