A. i, ii, iii and iv
Step-by-step solution
The human respiratory system is anatomically divided into the upper and lower respiratory tracts.
The upper respiratory system includes the structures located outside the chest cavity, which are the external nares, nasal cavities, internal nares, and the pharynx (including the nasopharynx).
The lower respiratory system includes the structures located within or entering the chest cavity, which are the larynx, trachea, bronchi, bronchioles, and lungs.
Therefore, external nares (i), nasal cavities (ii), internal nares (iii), and nasopharynx (iv) are parts of the upper respiratory system.
Answer: i, ii, iii and iv
The upper respiratory system includes the structures located outside the chest cavity, which are the external nares, nasal cavities, internal nares, and the pharynx (including the nasopharynx).
The lower respiratory system includes the structures located within or entering the chest cavity, which are the larynx, trachea, bronchi, bronchioles, and lungs.
Therefore, external nares (i), nasal cavities (ii), internal nares (iii), and nasopharynx (iv) are parts of the upper respiratory system.
