False
Breathing continues during swallowing.
False
Match the following parts of the lower respiratory tract with their description:
Trachea = Tubular structure connecting the larynx to the bronchi Bronchi = Site of gas exchange Bronchioles = Divisions of the bronchi Alveoli = Air sacs responsible for gas exchange

Larynx is pushed cranially = During swallowing Breathing stops = During swallowing Soft palate seals off the nasopharynx = During swallowing Epiglottis uncovers the airway = During inhalation
Match the following parts with their function during deglutition:
Epiglottis = Covers the airway Larynx = Pushed cranially Soft palate = Seals off the nasopharynx Trachea = Responsible for gas exchange
Match the following structures with their location in the lower respiratory tract:
Trachea = Connecting the larynx to the bronchi Bronchi = Divided into bronchioles Bronchioles = Divided into alveolar ducts Alveoli = Responsibly for gas exchange
