ANATOMY

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: -Pneumonia is an infection of the lungs that may be caused by bacteria, viruses, or fungi. The infection causes the lungs’ air sacs (alveoli) to become inflamed and fill up with fluid or pus. That can make it hard for the oxygen you breathe in to get into your bloodstream.

Detailed explanation-4: -Pneumonia is an inflammation of the lung parenchyma.

Detailed explanation-5: -Pneumonia is an infection that affects one or both lungs. It causes the air sacs, or alveoli, of the lungs to fill up with fluid or pus. Bacteria, viruses, or fungi may cause pneumonia.
