What does pneumonia characterize?

Pneumonia is characterized as a respiratory disease that involves inflammation of the lungs, most commonly due to infection. This inflammation can make it difficult for the lungs to function properly, impacting the body’s ability to absorb oxygen and remove carbon dioxide. The inflammation leads to symptoms such as cough, fever, chills, and difficulty breathing. It is important to identify pneumonia as a condition specifically affecting the respiratory system and lungs, which distinguishes it from other conditions that pertain to different organ systems, such as skin, digestive, or throat infections.
