Mucus purulent sputum

Sputum is an acute and chronic tracheobronchitis. Cough, sputum, asthma, and inflammation are common symptoms of lower respiratory tract infections. In the human's respiratory tract, many small ciliated wheat waves are heading in the direction of the mouth, slowly pushing the dirty things out, and when they are pushed to the throat, the person will cough and spit. Acute tracheobronchitis begins with a single dry cough or a small amount of mucus and sputum. With the development of the disease, the cough worsens, secretions gradually increase, and the sputum is mucopurulent.
