Give two examples for respiratory diseases.

Explanation

Disorders of respiratory system.
Asthma: Asthma is a difficulty in breathing caused due to inflammation of bronchi and bronchioles. Symptoms include coughing, difficulty in breathing and wheezing.
2) Emphysema : It is a chronic disorder in which alveolar walls are damaged and their walls coalesce due to which respiratory surface area of exchange of gases is decreased. One of the major causes of this is smoking of tobacco.
3) Bronchitis : Bronchitis is the inflammation of the bronchi, resulting in the swelling of mucus lining of bronchi, increased mucus production and decrease in the diameter of bronchi. Symptoms include chronic cough with thick sputum.
4) Pneumonia : The infection of lungs caused by Streptococcus pneumoniae and also by certain Virus, Fungi, Protozoans and Mycoplasmas. Symptoms include inflammation of lungs accumulation of mucus in alveoti and impaired exchange of gases, leading to death if untreated. Occupational dissorders : These are caused by exposure of the body to the harmful substances.
E.g.: i) Aibestosis: It occurs due to chronic exposure to asbestos dust in the people working in asbestos industry.
ii) Silicosis : It occurs because of long term exposure to silica dust.
iii) Siderosis : It occurs due to deposition of iron particles in tissues.
iv) Black lung disease : It develops from Inhalation of coal dust.
