Published	06/22/2023	The {{c1::pulmonary acini}} is the portion of the lungs supplied by the {{c2::terminal bronchiole and all its branches}}.
Published	06/22/2023	2 types of blood vessels merge at the level of the {{c1::respiratory bronchioles}}.
Published	06/22/2023	There are {{c1::fewer}} type 1 alveolar cells than type 2. Type 2 are alveolar {{c1::macrophages}} in ducts and type 1 are alveolar cells with a …
Published	06/22/2023	The nasal cavity mucosa is lined by {{c1::pseudostratified ciliated columnar}} epithelium interspersed with {{c1::goblet cells}} resting on a prominen…
Published	06/22/2023	The pharynx is a part of both the {{c1::digestive}} and {{c1::respiratory}} tracts.
Published	06/22/2023	The epithelium of the epiglottis transitions from stratified {{c1::squamous}} to stratified {{c1::columnar}}.
Published	06/22/2023	The larynx has {{c1::respiratory}} epithelium but over the vocal folds it is {{c1::stratified squamous}}. At the junction of the folds there is {{c1::…
Published	06/22/2023	Clara cells are {{c1::exocrine}} cells that secrete components of {{c1::surfactant}}. They lay within the epithelium of the {{c1::terminal bronchioles…
Published	06/22/2023	{{c1::Pseudostratified ciliated columnar}} epithelium lines the nasal cavity, intrapulmonary bronchi, and the trachea.
Published	06/22/2023	Respiratory bronchioles have {{c1::simple cuboidal}} epithelium.
Published	06/22/2023	The three layers of the respiratory tract are the {{c1::mucosa}}, {{c1::lamina propria}}, and {{c1::adventitia}}.
Published	06/22/2023	The distinguishing feature between the intrapulmonary bronchi and the extrapulmonary bronchi is that the intrapulmonary have {{c1::irregular plates of…
Published	06/22/2023	Pulmonary surfactant prevents alveolar collapse by {{c1::decreasing surface tension}}. It forms a layer of {{c1::phospholipids and proteins}} that cov…
Published	06/22/2023	{{c1::Mast cells}} in the bronchus associated lymphoid tissue when stimulated can lead to {{c1::bronchoconstriction and edema}}.
Published	06/22/2023	{{c1::Interalveolar pores of Kohn}} are small holes in the alveolar wall that allow the passage of air.
Published	06/22/2023	Terminal bronchioles are the {{c1::last part of the bronchioles}} while respiratory bronchioles branch into {{c1::alveolar ducts and alveoli}}.
Published	06/22/2023	With the exception of the {{c1::trachea}}, there are no glands in the submucosa of the respiratory tract.
Published	06/22/2023	{{c1::Bronchioles}} have no cartilage.
Published	06/22/2023	{{c1::Lymphoid nodules}} in the respiratory tract are found in the {{c2::secondary bronchi}}.
Published	06/22/2023	The lung {{c1::blood-air barrier}} contains 3 cells:1. {{c2::Endothelial cells}}2. {{c2::Type I pneumocytes}}3. {{c2::Basement membrane}}
Published	06/22/2023	The {{c1::conducting}} portion is where gas travels through.The {{c2::respiratory}} portion is where gas exchange occurs.
Published	06/22/2023	{{c1::Hyaline cartilage}} in the {{c2::conducting portion}} keeps the airway open. There is no {{c1::hyaline cartilage}} in the {{c2::bronhioles}}.
Published	06/22/2023	The wall of the {{c1::larynx}} is made up of {{c2::hyaline}} and {{c2::elastic}} cartilage.
Published	06/22/2023	{{c1::Dust}} cells are also called {{c2::alveolar macrophages}}.
