Circle True or False. Four processes - pulmonary ventilation, external respiration, transport of respiratory gases, and internal respiration must all occure in order for the respiratory system to function fully.	True
The upper respiratory structures include the nose, the larynx and the _________?	Pharynx
Circle the Correct term. The thyroid cartilage/oropharynx is the larges and most prominent of the laryngeal cartilages.	Thyroid cartilage
Circle True or False. The epiglottis forms a lid over the larynx when we swallow food: it closes off the respiratory passageway to incoming food or drink.	True
Air flows from the larynx to the trachea, and then enters the?	Left and right main bronchi
