Question

question 16
spiro/metry is used to evaluate:
o lung blood flow
o tuberculosis activity
o lung size
o lung capacity

question 17
the laryngopharynx extends from the oral pharynx down to:
o epiglottis
o voice box
o soft palate
o hard palate

question 18
epiglottis literally means:
o upon/tongue
o over/tonsil
o below/palate
o greater/mouth

Explanation:

• Question 16: Spirometry measures the volume of air inhaled and exhaled, which is related to lung capacity. Lung blood flow is measured by other techniques (e.g., perfusion scans), tuberculosis activity is diagnosed through sputum tests, cultures, etc., and lung size is more about anatomical dimensions (not directly measured by spirometry).
• Question 17: The laryngopharynx (lower part of the pharynx) extends from the oral pharynx down to the voice box (larynx). The epiglottis is a flap over the larynx, the soft palate is part of the roof of the mouth (related to the nasopharynx/oral pharynx junction in some aspects), and the hard palate is the bony part of the roof of the mouth (not the lower boundary of the laryngopharynx).
• Question 18: "Epi -" means upon/over, and the epiglottis is a structure that covers the glottis (related to the tongue - area in terms of its position during swallowing to prevent food from entering the trachea). "Tonsil" (tonsillectomy is removal of tonsils, not related to epiglottis root meaning), "palate" (epi - is not related to below palate), "greater/mouth" (no etymological link).

Answer:

• Question 16: Lung Capacity
• Question 17: voice box
• Question 18: upon/tongue
