Answer: C

Explanation:

The airway is divided into two different anatomical locations; the upper airway and lower airway. The upper airway starts where air enters the body, nose (Nares) and the mouth. Air will pass through the nose and is filtered and warmed before passing through the remainder of the upper airway and entering the lower airway. The upper airway ends at the Cricoid cartilage, the distal end of the larynx. The Thyroid cartilage is located at the proximal end of the larynx.
