Histology - Respiration Images Flashcards
Hyaline cartilage and trachealis mm - patency support
Kulchitsky cells - Amine Precursor Uptake & Decarboxylation (AUPD) - neuroendocrine cells
Smooth muscle, no cartilage, and aveoli. Is a branchiole.
Visceral pleura - Mesothelium (M, simple squamous epithelium) and thin layer of loose connective tissue
Brounchus Associated Lymphatic TIssue - BALT
Phagocytotic cells - dust cells - TEM, c= capillar, e = RBC, m = macrophage
Emphysema - breakdown of interalveolar septum, ‘air trapping’ in large spaces, reduced air exchange.
Pseudostratified Epi, seromucous glands, hyaline cart. NO aveoli, so much be Trachea or Main Bronchus
Congenital Hiatal (diaphragmatic) Hernia - associated with Potter’s Sequence (Oligohydramnios)
Fibroblast - Synthesizes CT ECM
Clara cells (CC, Cl) - dome shaped. Increase as descend branchiolar tree, secrete surfactant, lysozyme, anti-inflammatory ptoreins
Cuboidal epithelial cells - account for 60% of alveolar lining cells - line 5% of alveolar lumen
Lung small cell carcinoma
Opening of alveolar duct (into alveolar sac)
Bronchioles (incl. terminal bronchioles) - Simple cuboidal epithelium, NO goblet cells!
Alveolarstem cells - give rise to type I & II cells
Trachea
Thin Interalveolar Septum and RBC
Smooth muscle in branchioles, incl. terminal branchioles.
normal interalveolar septum
Smooth muscle in 2’ and 3’ bronchi
Endothelial cell injury - sepsis
Pulmonary hypoplasia (left lung) - associated with Congenital Hiatal (diaphragmatic) Hernia
Intrapulmonary Bronchus
TEM - Lamellar bodies - syntheize, store, and secrete surfactant
1 - alveolar sac 2 - respiratory bronchiole 3- alveolar duct 4 - alveolus 5 - terminal bronchiole
Pulmonary burns (fire) - damage entire wall, edema, fluid in alveolar spaces, necrotic cells
Smooth muscle, no cartilage, and aveoli. Is a branchiole.
Macrophage - Phagocytosis, Antigen presentation, inflammatory responses
Alveolar macrophages (M) - black specks
Alveolar duct (black line) and alveolar sacs (AS)
Alveolar Patency - Elastic fibers. Ma = macrophage
Mucociliary escalator - synchronized beating of cilia sweep mucous coat upwards toward pharynx. CC - ciliated cells, GC - goblet cells
Alveolar injury - toxic fumes
Branchiole
Plasma Cell - B lymphocyte derivative - Secretes antibodies - immunoglobulins or Ig molecules
Terminal bronchioles in pseudoglandular period - end 16 weeks. (cuboidal epithelium) Capillaries present (not associated). No respiratory bronchi or alveoli
