Pneumonia and Related Terms
Pneumonia is an infectious condition primarily involving the alveoli in the lungs, which become inflamed and fill with fluid, leading to impaired gas exchange. The condition can result from bacterial, viral, fungal, or parasitic infections. Pneumonitis, on the other hand, is a general term for lung inflammation, which can be caused by factors other than infection, such as inhalation of allergens or irritants. Although they are related to respiratory illnesses, pneumococcus refers to the bacteria Streptococcus pneumoniae, which is a common cause of pneumonia; pneumothorax is a condition where there is air or gas in the pleural space causing lung collapse; and pleurisy is the inflammation of the pleura that can cause sharp chest pain with breathing.
The correct answer to which term has the same meaning as pneumonia, based on this information, is pneumonitis, which is another term for lung inflammation.
