The respiratory system begins with the nose and mouth and continues through airways to the lungs, where oxygen from the atmosphere is exchanged for carbon dioxide from the bodyís tissues.
The human body cannot survive for more than a few minutes in an environment that lacks oxygen. Oxygen is required for the normal functioning of all living body cells. Infection is always a potential threat to the lungs because this organ is in constant contact with the outside air and therefore is constantly exposed to infectious agents due to environmental pollution and unhygienic conditions.
Respiratory system disorders are broadly classified into two major groups. Upper Respiratory Tract Infection (URTI) such as the common cold, sore throat, sinusitis, pharyngitis, laryngitis, tonsillitis, and tracheitis. They constitute 10-20% of all practice consultation. Lower Respiratory Tract Infection (LRTI) like bronchial asthma, acute and chronic bronchitis, emphysema, pneumonia, pleuritis, etc. All these disorders are caused by allergy or viral and bacterial infections.
In modern system of medicine, the drugs often used in the treatment are antiallergics, antibiotics, bronchodilators, corticosteroides, antitussive, antihistamines, expectorants, mucolytics, decongestants, etc.
