Example respiratory system test questions

Which muscle is the primary muscle of inhalation?The diaphragm. It contracts and flattens to enlarge the thoracic cavity and draw air into the lungs.

True or false: Oxygen moves from the alveoli into the blood mainly by diffusion.True. Gas exchange happens across thin alveolar and capillary walls, moving down a concentration gradient.

Which alveolar cells produce surfactant, and what does it do?Type II alveolar cells produce surfactant. It lowers surface tension so alveoli do not collapse during exhalation.

Which structure covers the larynx to keep food out of the trachea during swallowing?The epiglottis. This flap closes over the airway so swallowed material goes into the esophagus.

Which part of the brainstem sets the basic breathing rhythm?The medulla oblongata. It responds mainly to rising blood carbon dioxide and pH and signals the breathing muscles.

Take the test and review
