Definition of Pneumonia and Bronchitis
- Pneumonia: A serious infection that inflames the air sacs in one or both lungs, often filled with fluid or pus.

✔ Pneumonia = Lung infection (alveoli affected)
✔ Bronchitis = Airway inflammation (bronchi affected)
Pronunciation
Understanding pronunciation helps identify the difference between pneumonia and bronchitis in medical conversations:
- Pneumonia → /nuːˈmoʊniə/ (noo-MOH-nee-uh)
- Bronchitis → /brɒŋˈkaɪtɪs/ (brong-KY-tis)
These terms are commonly used in hospitals, Google Health searches, and medical content on YouTube and Meta health pages.
