Pneumonia is a medical condition characterized by inflammation primarily affecting which structures within the body?

Explanation

Pneumonia is a medical condition characterized by inflammation primarily affecting the tiny air sacs, called alveoli, within the lungs, often caused by an infection from bacteria, viruses, or, less commonly, fungi. This inflammation can cause the alveoli to fill with fluid or pus, significantly interfering with the lungs’ normal ability to efficiently exchange oxygen and carbon dioxide, potentially resulting in symptoms like coughing, fever, and difficulty breathing. Pneumonia can range considerably in severity, from a relatively mild illness manageable at home to a serious, potentially life-threatening condition requiring hospitalization, particularly among very young children, older adults, or those with weakened immune systems.
