XII - Respiratory System Flashcards
Lungs: Conducting Portion
trachea, main bronchi, lobar bronchi, segmental bronchi, terminal bronchioles
Lungs: Respiratory Portion
respiratory bronchioles, alveolar ducts, alveolar sacs, alveoli
Epithelium: trachea, main bronchi, lobar bronchi, segmental bronchi
pseudostratified ciliated columnar epithilium, goblet cells, submucous glands, hyaline cartilage
Epithelium: bronchioles
simple ciliated columnar to cuboidal, Clara cells
Epithelium: terminal bronchioles
simple cuboidal, ciliated, Clara cells
Epithelium: respiratory bronchioles
simple cuboidal, ciliated, Clara cells, scattered alveoli
Epithelium: alveolar ducts, alveolar sacs
simple cuboidal between many alveoli
Epithelium: alveoli
type I and II alveolar cells (pneumocytes)
Respiratory Tract: rhythmically moving back and forth to eliminate dust and germs from nasal passages
ciliated cells
Respiratory Tract: chemosensory
brush cells
Respiratory Tract: secretes mucus
goblet cells
Respiratory Tract: capable of regeneration and repair
basal cells
Respiratory Tract: metabolize airborne toxins
Clara cells / exocrine bronchiolar cells
Respiratory Tract: lines the alveoli
type I pneumocytes
Respiratory Tract: secretes surfactant and store it in lamellar bodies, capable of regeneration and repair
type II pneumocytes
Respiratory Tract: alveolar macrophage, antigen presenting cells
dust cells
Respiratory Tract Components: trachea, main bronchi, lobar bronchi, segmental bronchi, terminal bronchioles
goblet cells, submucous glands, smooth muscle, elastic fiber
Respiratory Tract Components: terminal bronchioles, respiratory bronchioles
smooth muscle, elastic fiber
Respiratory Tract Components: alveolar sacs
elastic fiber
Drug given to women to hasten surfactant production
corticosteroids (dexa-/betamethasone)
Determines fetal lung maturity from amniotic fluid sample
L:S ratio (lecithin : sphingomyelin)
Cells seen in lungs in the presence of CHF
hemosiderin-laden macrophages (heart failure cells)
Respiratory Tract: equalize air pressure in alveoli, permit collateral circulation of air when bronchiole is obstructed
alveolar pores of Kohn
Respiratory Tract: surfactant layer, type I pneumocytes, fused basal laminae of cells lining alveolus and endothelial cells, capillary endothelial cells
blood-air barrier
Imbalance of pressures in pulmonary capillaries causing edema
hydrostatic - out, oncotic - in
Protein important in the maintenance of adequate oncotic pressure to prevent edema
albumin
