PPT 03 and PPT 04 (Respiratory) Flashcards
most important diseases in which the lesion is centered primarily in bronchioles
feline asthma, equine heaves
bronchioles do not have these structures
cartilage, glands, goblet cells, mucociliary apparatus
Chronic bronchiolar injury induces
goblet cell metaplasia
other terms for equine heaves
Recurrent airway Obstruction, Equine chronic obstructive pulmonary disease
characterized by airflow obstruction that eventually leads to alveolar emphysema
heaves
abdominal muscle hypertrophy of horse with heaves
heave line
color of a normal lung varies depending on several factors such as
ex-sanguation, hypostatic congestion, autolysis, postmortem imbibitions
where oxygen and carbon dioxides are exchanged in the lung
air blood barrier
deposition and retention of carbon particles in the lung
anthracosis
generic term used to denote deposition of any particle such as carbon in anthracosis
pneumoconiosis
a passive accumulation of blood in pulmonary vessels and capillaries
pulmonary congestion
allergic disease to inhaled dust and Mucus plug allergens that causes mild bronchiolar inflammation but severe goblet cell metaplasia and airway obstruction
heaves
alveolar macrophages filled with hemosiderin pigment from phagocitized RBCs
heart failure cells
heart failure cells are best demonstrated by?
prussian blue stain
most common exogenous pigmentation in the lungs of domestic animals
anthracosis
occurs when an abscess erodes a major pulmonary vessel
ruptured pulmonary aneurism
common causes of pulmonary hemorrhages in domestic animals
congestive heart failure, pulmonary contusion, lung embolism, pulmonary aneurism
characterized by accumulation of fluid in pulmonary interstitium and alveoli.
pulmonary edema
Underlying mechanisms responsible for lung edema
increased vascular permeability, increased hydrostatic pressure, lymphatic obstruction
formed when the protein-containing fluid in airways is mixed with air following vigorous inspiratory movements
foam
