Answer 1

In chronic bronchitis, mucus production is increased, leading to inflammation and fibrosis of the mucosal lining of the bronchial tree.

Step-by-step explanation:

In chronic bronchitis, mucus production is increased, and this leads to the inflammation and fibrosis of the mucosal lining of the bronchial tree. Excessive mucus production in the bronchial tubes narrows the air passages and makes it harder to breathe. The thickened mucus can also lead to coughing and other respiratory symptoms.
