What is a bronchial secretion?
Bronchial secretions are mainly produced by goblet cells and submucosal glands but also small amounts of surfactant from clara cells and some other fluids are part of the airway epithelium fluid.
What causes increased bronchial secretions?
It develops in response to long-term irritants on the bronchial mucosa. Important irritants include cigarette smoke, dust, smoke, and fumes; other causes include respiratory infection, particularly in infancy, and exposure to dampness, sudden changes in temperature, and fog.
What causes pulmonary secretions?
Environmental irritants such as cigarette smoke and pollutants can cause the goblet cells to produce and secrete mucus while damaging the cilia and structures of the airways. Exposure to these irritants, especially if you already have a lung disease, can substantially increase your risk of excess mucus in the lungs.How do you get rid of lung secretions?

What is the life expectancy of someone with bronchiectasis?
Most people diagnosed with bronchiectasis have a normal life expectancy with treatment tailored to their needs. Some adults with bronchiectasis developed symptoms when they were children and live with bronchiectasis for many years.
