The pharynx is the common passage for food and air, with the oropharynx being a part of it.
The larynx is a cartilaginous box which helps in sound production and is hence called the sound box.
The trachea is a straight tube extending up to the mid-thoracic cavity. The trachea, primary, secondary and tertiary bronchi, and initial bronchioles are supported by incomplete ('C' shaped) cartilaginous rings.
