What are two diseases associated with the respiratory system?

Two diseases associated with the respiratory system are Asthma and chronic obstructive pulmonary disease (COPD). Asthma is a chronic condition characterized by inflammation and narrowing of the airways, leading to difficulty in breathing, wheezing, and coughing. COPD, which includes emphysema and chronic bronchitis, is a progressive disease that obstructs airflow and is primarily caused by long-term exposure to irritants like tobacco smoke. Both conditions can significantly impact a person's quality of life and require ongoing management.
