various respiratory disorders and with their explanation
Answers
Answer:
Common Respiratory Disorders Include:
Chronic Bronchitis - Any irritant reaching the bronchi and bronchioles will stimulate an increased secretion of mucus. In chronic bronchitis the air passages become clogged with mucus, and this leads to a persistent cough.
Emphysema - The delicate walls of the alveoli break down, reducing the gas exchange area of the lungs. The condition develops slowly and is seldom a direct cause of death.
Asthma - Periodic constriction of the bronchi and bronchioles makes it more difficult to breathe.
Chronic Obstructive Pulmonary Disease (COPD) - Irritation of the lungs can lead to asthma, emphysema, and chronic bronchitis and people can develop two or three of these together.

Respiratory disorder, or respiratory disease, is a term that encompasses a variety of pathogenic conditions that affect respiration in living organisms. Respiration makes gas exchange possible in higher organisms. The gas exchange involves taking oxygen into the body and expelling carbon dioxide. Respiratory disease occurs in the respiratory tract, which includes the alveoli, bronchi, bronchioles, pleura, pleural cavity, trachea and the nerves and muscles of breathing.
There are three main types of respiratory disease: airway diseases, lung tissue diseases and lung circulation diseases. Airway diseases affect the tubes that carry oxygen and other gases into and out of the lungs. Airway diseases usually result in narrowing or blocking of the passageways. Lung tissue diseases affect the structure of lung tissue and result in scarring or inflammation of the lung tissue. This, in turn, makes breathing difficult. Lung circulation diseases occur when the blood vessels in the lungs become clotted, inflamed or scarred. These diseases affect the ability of the lungs to receive oxygen and produce carbon dioxide, and they may affect the functioning of the heart.
