What is Respiratory System Parts and Functions about?
The nose and nasal cavity warm, moisturize, and filter air before it reaches the lungs. The nasal cavity contains hairs and mucus that trap contaminants. The mouth can supplement nasal breathing but does not filter air as well. The pharynx carries inhaled air down to the larynx and diverts it to the trachea or esophagus. The larynx contains vocal folds that allow speech and is located above the trachea in the neck. The trachea connects the larynx to the bronchi and remains open via cartilage rings.
