In brief: Lower respiratory

Upper respiratory infections involve upper airways such as throat, nasal cavity, paranasal sinuses, eustachian tubes, trachea as, nd bronchi.
When the disease process in the bronchi, or bronchitis, continues, it could begin to involve lower airways in the lung tissues, which is then more advanced lower respiratory infections or pneumonia.
