- 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

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
