Understanding Pneumonia

Pneumonia is a lung infection caused by various microbes, leading to inflammation and fluid in the lungs. It can be caused by viruses, bacteria, fungi, and mycobacteria. Pneumonia is classified by how it is acquired: community-acquired, hospital-acquired, ventilator-associated, or aspiration. Symptoms include shortness of breath, chest pain, and cough. Diagnosis involves chest x-rays and physical examination. Treatment typically involves antibiotics and symptom management.

What is the primary function of the alveoli in the lungs?
