Shoshanna is asked to spell the term that describes tiny air sacs with thin walls located at the end of the bronchioles. How should she spell it?

The tiny, thin-walled air sacs at the ends of the bronchioles are called alveoli. The correct spelling is “alveoli,” so Shoshanna should choose A. “Glottis” refers to a structure in the throat, not the air sacs in the lungs.
