Your windpipe, or trachea, is a component of your airway system. Your lungs get oxygen-rich air through channels called airways. Additionally, they transport carbon dioxide, a waste gas, from your lungs. Air enters your body through your nose, passes through your larynx, and then descends through your windpipe. Or, to put it another way, the trachea is a little tube that joins the larynx to the lungs' bronchi. It's also referred to as a "windpipe."
