Picture of Airway
The airway is the part of the anatomy that allows air to flow into and out of the lungs. The nose and mouth form both the entryways and exits for air flow. After inhaling, air flows past the back of the throat, or pharynx. It then flows past the voice box, or larynx. Air then travels down the pipe, or trachea, heading toward the lungs. Tubes called bronchi receive the air.
