What is one of the effects of inflammation in the lungs?

One of the effects of inflammation in the lungs is the thickening of airway walls. This occurs as a response to harmful stimuli, such as infections or irritants, leading to the activation of the immune system. Inflammatory cells infiltrate the airway tissues, which produces various substances, including cytokines and growth factors. These substances promote swelling and the proliferation of cells within the airway walls, resulting in increased thickness.

Thickened airway walls can contribute to respiratory issues such as reduced airflow and increased difficulty in breathing, which can be seen in conditions like asthma or chronic obstructive pulmonary disease (COPD). Understanding this effect is crucial as it underscores the importance of managing inflammation within the lungs to maintain respiratory health.
