The respiratory system oversees gaseous exchange activities in the human body system by supplying oxygen to the body organs via breathing and getting rid of carbon dioxide as a respiratory waste product. These functions occur in different zones, which include the conducting and respiratory zone. It is vital for it provides oxygen necessary for chemical body reactions.
Answer and Explanation.
The correct choice is b. Bronchus, nasal cavity, trachea, pharynx.
The conduction zone is an area within the respiratory system that facilitates the movement of air in and out of the lungs while ensuring the removal of foreign substances from the air. Thus, it includes organs such as the nose, which passes air to the pharynx and larynx. Then it moves to the trachea and finally to the bronchi.
Whereas the respiratory zone is the area where the gaseous exchange occurs, thus is comprised of the alveolar ducts and alveoli.
