The airway passages normally produce secretions which it uses to trap debris and using the cilia in the epithelium, remove the offending particles. During respiratory tract infections, the secretions become a medium for bacteria to grow in and this secretion is increased- now called phlegm.
It really is stored in the nose. The lining of the respiratory tract (including the nose) produces a mucous (phlegm). This traps dust and other stuff that doesn't belong further in the tract. This is moved slowly out with its' dust.
phlegm
Phlegm will go into your stomach and the acid in your stomach will dispose of it naturally, just the way it does when you swollow food. It is not harmful to swallow phlegm.
Phlegm helps to trap foreign materials such as dirt, microbes and pollutants from going further into the body. Phlegm comes in different colors from shades of green to white.
I have a cough then suddenly, the phlegm was blocking my throat.
no
clear phlegm is normal. Red,Green,yellow is not normal---get help.
Cough medicines may help either to control coughing or loosen the phlegm.
No, phlegm cannot be eliminated by passing gas. Phlegm is a thick mucus produced in the respiratory system, while passing gas involves the release of air from the digestive tract. The two processes are unrelated, and phlegm is typically cleared through coughing or swallowing.
phlegm
The phlegm comes from your lungs. It may mix with saliva in your mouth.
I feel that when I drink beer while I am a bit sick I do produce more phlegm
