Common lung diseases. The clinical manifestations are diverse. The most common infectious pneumonia includes systemic symptoms such as fever, weakness, and general discomfort, as well as local symptoms such as cough, sputum, chest pain, and shortness of breath. Pneumonia is an inflammation of the lung parenchyma. The lung parenchyma is the part of the lung where gas exchange occurs, mainly referring to the terminal respiratory units composed mainly of alveoli. Inflammation may spread throughout the lung or be localized.

Under the microscope, dilated blood vessels can be seen in the inflamed area, and there is fluid exuded from the blood vessels in the interstitial tissue around the blood vessels and the alveoli. The exudate is rich in inflammatory cells such as polymorphonuclear leukocytes, and the alveoli may be filled with inflammatory exudate (consolidation). Pneumonia can be caused by a variety of factors, including physical, chemical or biological factors. For example, if the chest is exposed to radiation during radiotherapy, it can cause radiation pneumonia, and inhalation of toxic gases can cause chemical pneumonia. However, these non-infectious pneumonias are relatively rare, and most cases are infectious pneumonia, which is caused by pathogenic microorganisms such as bacteria and viruses. However, certain special infections (such as tuberculosis) and conditions in which inflammation leads to significant tissue necrosis and cavity formation (such as lung abscess) are not customarily referred to as pneumonia.
