Chap 12 - Pathology

Acute viral infection in infants and children characterized by obstruction of the larynx, barking cough and stridor
Cause by influenza or respiratory syncytial virus (RSV)

Acute infection of the throat and upper respiratory tract caused by the diphtheria bacterium

Nosebleed

Highly contagious bacterial infection of the pharynx, larynx and trachea caused by Bordetella pertussis
aka whooping cough

Chronic inflammatory disorder with airway obstruction caused by bronchial edema, bronchoconstriction and increased mucus production

Chronic dilation of a bronchus secondary to infection in the lower lobes of the lung

Inflammation of the bronchi persisting over a long time

Inherited disorder of exocrine glands resulting in thick mucous secretions that do not drain normally

Incomplete (atel/o) expansion (-ectasis) of alveoli; collapsed, functionless, airless lung or portion of a lung. Caused by tumor or other obstruction of the bronchus or poor respiratory effort

Hyperinflation of air sacs with destruction of alveolar walls

Right ventricular hypertrophy and heart failure

Malignant tumor arising from the lungs and bronchi

Abnormal condition caused by dust in the lungs with chronic inflamation, infection and brochitis
asbestosis - asbestos
anthracosis - coal dust
silicosis - silica

Acute inflammation and infection of alveoli which fill with pus or products of the inflammatory reaction

Involves entire lobe of the lung
