12058414021	Alveoli first appear at?	17 to 19th generations aka transitional zone	4
12058414022	Which generations are in the respiratory zone?	20-22 are lined with alveolar ducts and sacs	5
12058414023	Which bronchioles have alveoli?	Respiratory bronchioles have some...	6
12058414024	What comprises the acinus?	10-12 of respiratory bronchioles which each have about 100 ducts and 2000 alveoli sacs	7
12058641037	Trachea is supported by	Ventrolateral c shaped cartilage and dorsal smooth muscle	8
12058641038	What are cartilage rings replaced by in the lungs	Irregular shaped cartilage plates that surround the bronchi as opposed to the C shapes	9

12058641040	What secretes mucus?	Goblet cells	11
12058641041	What replaces goblet cells in the respiratory zone?	Club cells that secrete proteins, lipids, glycoproteins and modulators of inflammation	12
12058641042	What protein do club cells secrete?	Surfactant apoproteins	13
12064763333	Interalveolar communication	Pores of khan	14

12064763335	Which cell is larger? Which cell is more abundant?	Type 1 covers 95% of alveoli because it is larger even though type II are twice as abundant	16
