(Exchange of O2 and CO2) The Lungs (1) The essential organs of respiration; Two in number; Two lobes on the left ,three lobes on the right; The organs of gas exchange : 1. Conduct for air flow. 2. Surface for movement of oxygen into the bl- ood and carbon dioxide out of the blood. The lungs (2) Common diseases in the lungs (1) Congenital abnormalities; Atelectasis; Vascular disease; Pulmonary disease: 1.Infections of the lungs. 2.Interstitial disease of the lungs 3.Diseases of introgenic origin 4.Neoplastic disease of the lungs Common diseases in the lungs (2) Pulmonary disease Emphysema Bronchiectasis Infections of the lung Lung abscess Pulmonary tuberculosis Neoplastic disease of the lung Lung cancer Contents 1.Bronchiectasis Etiology: The pathogenesis a number of predisp- osing factors, both congenital and ac- quired. Acquired infection of the lungs i s the major contributor, congenital fac- ors may also have a role. 1.Bronchiectasis Endobronchial obstruction with distal infection is considered to be significant in the development of bronchiectasis. The obstruction can exist either on the basis of intrabronchial or extrabronchi- al origin. 1.Bronchiectasis Intrinsic causes: 1.Retained purulent bronchial secretio- ns. 2.Thickened mucous plugs. 3.Obstruction from a foreign body. 4.Neoplasm. Extrinsic bronchial obstruction can occur fr
