How is phlegm formed?

Foreign bodies such as dust, bacteria and viruses inhaled by human body are captured by mucus secreted by relevant cells in bronchus, and then the mucus is continuously transported upward to a specific position through the regular movement of respiratory cilia to form sputum.

Sputum will stimulate the throat to produce cough reflex and spit it out, but if the amount is not large, it will stimulate swallowing reflex and swallow it directly into the stomach.

Classification of phlegm:
