Trachea. A passageway in your throat that carries air into and out of your lungs. Epiglottis. A strip of tissue in the back of your sound that keeps food out of your trachea..The trachea (or windpipe) is a wide, hollow tube that attaches the larynx (or voice box) to the bronchi of the lungs. It is an essential part of the body's airway and has the important purpose of rendering air flow to and from the lungs for respiration.
The answer would be "D. TRACHEA". It is because the first part of the pharynx which is the nasopharynx transports air from the nose down to your throat and eventually to the lungs where gas exchange between carbon dioxide and oxygen occurs.
