Bronchitis

Bronchitis is an inflammation of the mucous membranes of the bronchi (the greater and medium-sized airways that carry air flow from the trachea into the more distal parts of the lung parenchyma).[1][2][3] Bronchitis can be split up into two categories:  acute and chronic.[1][2][3][4] Acute bronchitis is characterized by the introduction of a cough or little sensation at the back of the can range f, with or perhaps without the development of sputum(mucus that is expectorated, or " coughed up", from the respiratory tract). Acute bronchitis often occurs during the course of an acute viral disease such as the common cold or influenza.  Viruses cause about 90% of serious bronchitis situations, whereas bacteria account for about 10%.[5][6] Chronic bronchitis, a type of chronic obstructive pulmonary disease (COPD), is seen as the presence of a productive cough that lasts for three months or maybe more per year for at least two years. Serious bronchitis generally develops as a result of recurrent injury to the air passage caused by inhaled irritants.  Cigarette smoking is the most frequent cause, accompanied by exposure to air flow pollutants such as sulfur dioxide or nitrogen dioxide,[7] and work-related exposure to respiratory system irritants.[6][8] Individuals exposed to cigarettes, chemical chest irritants, or who are immunocompromisedhave an increased risk of developing bronchitis.[9]

Asthma

Asthma (from the Ancient greek ἅσθμα,  ásthma, " panting" ) is known as a common chronic inflammatory disease of the airways characterized by adjustable and recurring symptoms, reversible airflow obstruction and bronchospasm.[2] Common symptoms include wheezing,  coughing, chest tightness, and shortness of breath.[3] Breathing difficulties is thought to be caused by a combination of genetic and environmental elements.[4] Its diagnosis is usually based upon the style of symptoms, response to remedy over time and spirometry.[5] It is clinically classified according to the frequency of symptoms, pressured expiratory volume level in one second (FEV1), and peak...
