Verified step by step guidance

Step 1: Understand the role of the respiratory conducting passageways. These structures include the nose, pharynx, larynx, trachea, bronchi, and bronchioles. Their primary function is to transport air to the lungs, not directly exchange gases with the blood.

Step 2: Review the process of gas exchange. Gas exchange occurs in the alveoli, which are tiny air sacs in the lungs. The alveoli are part of the respiratory zone, not the conducting passageways.

Step 3: Examine the functions of the conducting passageways. They filter particles from the air using structures like nasal hairs and mucus, humidify incoming air by adding moisture, and warm incoming air through blood vessels in the nasal cavity.

Step 4: Compare the listed functions in the question. Filtering particles, humidifying air, and warming air are all functions of the conducting passageways. Exchanging gases with the blood is not a function of these passageways.

Step 5: Conclude that the correct answer is 'Exchanging gases with the blood,' as this function is performed by the alveoli in the respiratory zone, not the conducting passageways.
