Published	01/14/2024	{{c3::Left}} heart failure may present with {{c1::hemosiderin-laden macrophages}}, known as {{c2::heart failure}} cells, in the lungs
Published	01/14/2024	The large airways of the {{c1::conducting}} zone of the lung consists of the nose, pharynx, larynx, trachea, and bronchi
Published	01/14/2024	Does the conducting zone of the lung participate in gas exchange? {{c1::No}}
Published	01/14/2024	{{c1::Cartilage}} and {{c2::goblet cells}} extend to the end of the {{c3::bronchi}} of the conducting zone
Published	01/14/2024	Airway smooth muscle cells extend to the {{c1::terminal bronchioles}} of the conducting zone (sparse beyond this point)
Published	01/14/2024	The smooth muscle of the conducting airways of the lung {{c1::relaxes}} in response to sympathetic activation of the {{c2::β2::typenumber}} adrenergic…
Published	01/14/2024	What is the effect of sympathetic innervation on the smooth muscle of the conducting airways of the lung?{{c1::Relaxation}}
Published	01/14/2024	Does the respiratory zone of the lung participate in gas exchange? {{c1::Yes}}
Published	01/14/2024	The alveolar walls are lined with epithelial cells called {{c1::type I}} and {{c1::type II pneumocytes}}
Published	01/14/2024	Type {{c1::II}} pneumocytes are responsible for synthesis of pulmonary {{c2::surfactant}}
Published	01/14/2024	Type {{c1::II}} pneumocytes have regenerative capacity for both type I and type II pneumocytes
Published	01/14/2024	The alveoli contain phagocytic cells called {{c1::alveolar macrophages (dust cells)}}, which clear debris and participate in the immune response
Published	01/14/2024	When a person is standing, pulmonary blood flow is lowest at the {{c1::apex (top)}} of the lungs
Published	01/14/2024	Type {{c1::I}} pneumocytes line the alveoli (97% of alveolar surfaces)
Published	01/14/2024	Type {{c2::I}} pneumocytes are {{c1::squamous}} cells; thin for optimal gas diffusion
Published	01/14/2024	Type {{c2::II}} pneumocytes are clustered, {{c1::cuboidal::shape}} cells
Published	01/14/2024	Type {{c1::II}} pneumocytes proliferate during lung damage
Published	01/14/2024	{{c1::Lamellar bodies}} are secretory organelles found in type II pneumocytes that release surfactant
Published	01/14/2024	In conditions that cause destruction of the {{c1::pulmonary vasculature}}, hemosiderin laden macrophages may be seen in the alveoli
