To these major symptoms of lung disease—coughing, dyspnea, and chest pain—may be added several others. Leads to limited airflow into and out if the lungs, with increased difficult in breathing The narrow, obstructed airways restrict normal airflow into and out from the lungs. Emphysema destroys the walls of the alveoli of the lungs, resulting in a loss of surface area available for the exchange of oxygen and carbon dioxide during breathing. The respiratory tract is the site of an exceptionally large range of disorders for three main reasons: (1) it is exposed to the environment and therefore may be affected by inhaled organisms, dusts, or gases; (2) it possesses a large network of capillaries through which the entire output of the heart has to pass, which means that diseases that affect the small blood vessels are likely to affect the lung; and (3) it may be the site of “sensitivity” or allergic phenomena that may profoundly affect function. Omissions? 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.

Mucous membranes line the sinuses. A Patient's Guide to Respiratory Disease Anatomy. Acute bronchitis; Bronchiolitis Respiratory tract diseases are diseases that affect the air passages, including the nasal passages, the bronchi and the lungs. There are two types of respiratory diseases and disorders: infectious and chronic. Diseases and conditions of the respiratory system fall into two categories: viruses, such as influenza, bacterial pneumonia, enterovirus respiratory virus; and chronic diseases, such as asthma and chronic obstructive pulmonary disease (COPD). Not infrequently, the patient may feel as one does when convalescent after an attack of influenza. The inflammation blocks the sinus openings and prevents the mucus from draining. Some lung diseases can lead to respiratory failure. A wheeziness in the chest may be heard. This article discusses the signs and symptoms of respiratory disease, the natural defenses of the human respiratory system, the methods of detecting respiratory disease, and the different diseases of the respiratory system. The air pressure pushes on the outside of the lung until it collapses. Emphysema (COPD) – Chronic Obstructive Pulmonary Disease, of which emphysema is one of, results in progressive destruction of the air sacs in the lungs and loss of respiratory membrane for oxygen exchange. 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. A person with active lung tuberculosis or with lung cancer, for example, may be conscious of only a general feeling of malaise, unusual fatigue, or seemingly minor symptoms as the first indication of disease. hbspt.cta._relativeUrls=true;hbspt.cta.load(189659, '3e44b554-d078-4cb1-bbbd-abb41d9abb0d', {}); hbspt.cta._relativeUrls=true;hbspt.cta.load(189659, 'd81c2b40-64cb-4f78-a901-2d949123900d', {}); When you select "Subscribe" you will start receiving our email newsletter.
