A productive cough is characterized by the presence of mucus or phlegm being expelled from the lungs during coughing. This type of cough is commonly referred to as a "wet cough." The production of sputum is indicative of conditions where there is excess mucus, often seen in infections or chronic respiratory conditions. A wet cough signifies that the airways are attempting to clear out secretions, which is an important physiological function, especially in cases of respiratory illness.

In contrast, a dry cough does not involve the production of mucus and is typically associated with conditions such as allergies or irritants. A chronic cough can be either productive or non-productive, lasting more than eight weeks and often requires investigation to determine its underlying cause. A hacking cough, usually described as a repetitive, dry cough, does not lead to the expulsion of mucus.

Thus, the type of cough that is specifically known for its production of mucus is the wet cough.
