Diseases of the mamalian Respiratory system are classified physiologically into obstructive (i.e. conditions which impede the rate of flow into and out of the lungs) and restrictive (i.e. conditions which cause a reduction in the functional volume of the lungs).

Anatomically, respiratory disease can be classified into upper and lower respiratory tract (most commonly used in the context of infectious respiratory disease), parenchymal and vascular lung disease.

Obstructive lung disease

• Emphysema
• Bronchitis
• Asthma
• Chronic obstructive pulmonary disease (COPD)
• Bronchiectasis

Restrictive lung diseases

• Fibrosis
• Sarcoidosis
• Alveolar Damage
• Pleural effusion

Infectious lung disease

• Upper respiratory tract infections
• Lower respiratory tract infections or Pneumonia
• Tuberculosis

Vascular lung disease

• Pulmonary Edema
• Pulmonary Embolism
• Pulmonary Hypertension

Respiratory tumors

• Lung cancer
