Question

which order correctly demonstrates the passage of oxygen from the outside air to the lungs? note: not all parts of the passage are included, look for the correct chronological order. lungs → primary bronchi → pharynx larynx → primary bronchi → pharynx nasal cavity → pharynx → primary bronchi pharynx → trachea → larynx

Explanation:

The respiratory system's pathway for oxygen starts at the nasal cavity (filters, warms, moistens air), then to the pharynx (common passage for air and food), and then to the primary bronchi (lead to the lungs). The first option has the wrong direction (should be to lungs, not from). The second option has incorrect order (pharynx should come before larynx in the air - entry path). The fourth option has an incorrect order (larynx is above the trachea in the airway, so trachea cannot come before larynx).

Answer:

nasal cavity → pharynx → primary bronchi
