Answer:
The structures that are part of the upper respiratory system are the nose, the pharynx, and the larynx.
Explanation:
The air enters through the nose and travels to the pharynx, which has three parts. The nasopharynx connects with the nose, the oropharynx connects with the mouth, and the laryngopharynx connects with the larynx. Then, the air goes to the larynx, where the vocal folds are. Once that it passes the vocal folds, the air is in the lower respiratory tract.
