 - Pharyngitis, Tonsillitis, Laryngitis
 - Pharyngitis
 - Inflammation of throat
 - Strep throat caused by streptococcus pyogenes bacterium
 - Sore throat, high fever, white patches on a dark red
 - Tonsillitis
 - Aggregates of lymphoid tissue (glands) become swollen and inflamed
 - Tonsillectomy:
 - removal of the tonsils
 - less common today b/c of known value of tonsils in immune responses
 - Laryngitis
 - Inflammation of larynx
 - Often results in inability to talk
 - Usually disappears I you rest your voice and treat infection

15.4 Disorders of the Respiratory Tract (Continued)
- Disorders of the Lower Respiratory Tract
 - Disorders of the Trachea and Bronchi
 - Choking
 - Caused by a blocked trachea
 - Heimlich maneuver may be used to clear blocked air way
 - Tracheostomy: insertion of a breathing tube into an incision mad in the trachea
 - Acute bronchitis
 - Acute = sudden onset
 - Inflammation of the primary and secondary bronch
 - Preceded by a viral infection that leads to a secondary bacterial infection
 - Symptoms: a deep non-productive cough that produces mucus and sometimes pus
 - Treatment: antibiotics
 - Chronic bronchitis
 - Chronic = long-term
 - Airways inflamed and filled with mucus
 - Cough that brings up mucus
 - Bronchi are damaged
 - Often caused by smoking (smoker’s cough)
 - Asthma
 - Disease of bronchi and bronchioles
 - Symptoms: wheezing, breathlessness, cough, expectoration of mucus
 - Airways are extremely sensitive to irritants such as animal dander, dust and cigarettes, and become inflamed
 - Smooth muscle undergoes spasms
 - No cure for asthma, just controlled with drugs
 - Diseases of the Lungs
 - Pneumonia
 - Infection of the lungs where bronchi or alveoli fill with thick fluid
 - Symptoms: high fever, headache, chest pain
 - Causes: bacteria, viruses, other infectious agents
 - Pulmonary tuberculosis
 - Caused by bacterium Mycobacterium tuberculosis
 - TB skin test shows if person has been exposed
 - Emphysema
 - Chronic and incurable
 - Alveoli are damaged and lung functioning diminished
 - Usually caused by smoking
 - Cystic Fibrosis
 - Genetic disorder
 - Increases mucus secretions and makes it hard to breathe
 - No cure
 - Most people affected with CF die by age 30
 - Pulmonary fibrosis
 - Build up of connective tissue in lungs, causing loss of elasticity
 - Reduces lung volumes
 - Lung cancer
 - 87% of lung cancers are associated with smoking
