Sure! Pneumonia is an illness where the tiny air sacs in your lungs, called alveoli, get inflamed, or swollen. This can happen due to infection by germs like bacteria or viruses. When the alveoli get inflamed, they can fill up with fluid and pus, which makes it hard for your lungs to take in oxygen. This can lead to symptoms like coughing, trouble breathing, chest pain, and fever. Basically, pneumonia affects how well your lungs work, making it difficult to breathe and causing discomfort.
Pneumonia is characterized by inflammation of alveolar wall and accumulation of fluid and pus in alveolar sacs of one or both lungs
