Alveolar space of acinus was invaded by bacteria that interacted with
the surfactant. This led to the activation of the cells that are localized in
the alveolar walls and on the surface. Name these cells:
Alveolar Macrophages
Clara cells
Alveolocytes type I
O Alveolocytes type II
O Endothelial cells
what is the function of the following?
Nasopharynx, oropharynx, laryngopharynx, glotti, epiglottis, trachea, tracheal cartilages bronchi, mucosa of trachea, submucosa of trachea and adventitia of trachea. Also Brochiole, alveolar duct, alveolar sac, alveolus, dust cell/macrophages.
Mucous membranes (pseudostratified ciliated columnar epithelia) line most upper respiratory tract structures. Although these membranes filter the air by trapping pathogens in mucus, they are very delicate. Pieces of food passing through the oropharynx and laryngopharynx could damage this type of epithelium. Predict which type of epithelium protects the lining of the oropharynx and laryngopharynx.
