In an asthma attack, the inflamed airways become irritated during inhalation. In severe bronchitis the mucous glands lining the bronchi enlarge greatly, and, commonly, 30 to 60 ml of sputum are produced in a 24-hour period, particularly in the first two hours after awakening in the morning.

These substances include cigarette smoke and other inhaled pollutants. Influenza Is a Viral Infection of the Respiratory Tract. Mucous membranes line the sinuses. During an asthma attack, smooth muscles that surround the airways spasm; this results in tightening of the airways, swelling and inflammation of the inner airway space (lumen) due to fluid buildup and infiltration by immune cells, and excessive secretion of mucus into the airways. Asthma sufferers wheeze, cough, and have difficulty breathing during an attack. Roaring: It is also called Hemiplegia Laryngis or Laryngismus paralyticus – this is a chronic disease due to paralysis, usually affecting the left side of the larynx in which an abnormal sound is produced during forced inspiration. For example, pulmonary embolism, the occlusion of a pulmonary artery by a fat deposit or by a blood clot that has dislodged from a site elsewhere in the body, can cause pleurisy.

The bronchioles of the lungs are the site where oxygen is exchanged for carbon dioxide during the process of respiration. The air pressure pushes on the outside of the lung until it collapses. It may become so severe as to immobilize the victim, and tasks such as dressing cannot be performed without difficulty. Because the symptoms of lung disease, especially in the early stage, are variable and nonspecific, physical and radiographic examination of the chest are an essential part of the evaluation of persons with these complaints.
