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 cannot effectively moisturize the air before it reaches the lungs.

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 a 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 the exchange site of gas cannot exchange between air and blood inferred from the air sacs.

What is the respiratory system?

The network of organs and tissues that aids in breathing is known as the respiratory system. It consists of your blood vessels, lungs, and airways. The respiratory system also includes the muscles that propel your lungs. Together, these components help the body circulate oxygen and eliminate waste gases like carbon dioxide. The respiratory system is in charge of receiving oxygen, eliminating carbon dioxide, assisting in the creation of speech, and detecting scents. The conducting zone and the respiratory zone are the two main functioning components of the respiratory system.
