Which facilitates removal of secretions from the broncho-pulmonary mucous membrane?

Explanation:
Expectorants help clear secretions from the broncho-pulmonary mucous membranes by thinning the mucus and promoting easier coughing up of phlegm. By increasing the water content of secretions, the mucus becomes less viscous, making it easier for the cilia to move it up and out of the airways. This improves mucociliary clearance and relieves chest congestion in productive coughs. The other classes don’t address mucus clearance: antivirals target viruses, DMARDs modify immune responses in autoimmune diseases, and COX-2 inhibitors reduce inflammation.
