Detailed explanation-1: -Pneumonia is a condition characterized by an infectious inflammation of the lung parenchyma and deposition of pus within the alveoli. Pneumonia can be caused by bacteria (e.g., Methicillin-resistant Staphylococcus aureus (MRSA)), fungi (e.g., pneumocystic cainii), and viruses (e.g., cytomegalovirus (CMV)).

Detailed explanation-2: -If a person has pneumonia, the alveoli in one or both lungs fill with pus and fluids (exudate), which interferes with the gas exchange. This is sometimes known as ‘consolidation and collapse of the lung’.

Detailed explanation-3: -Bacterial Pneumonia. Bacterial pneumonia is an acute inflammation and consolidation (exudate fills alveoli) of lung tissue caused by bacteria.

Detailed explanation-4: -Lung inflammation, also known as pneumonitis, can be caused by exposure to airborne toxins or irritants, respiratory infections, and lung diseases like asthma or chronic bronchitis. Symptoms may include wheezing, shortness of breath, chest pain, and coughing.
