How do the lungs get rid of the particles in the air that are trapped in the lungs?
In: Biology
1) particulate is embedded in mucus that is naturally produced to line our airways
2) small “hairs” (cilia) gradually push particulate-laden mucus up towards the trachea and throat
3) we either swallow or expel the particulate-laden mucus. coughing speeds this process up.
