How does my body usually get rid of mucus

HOW DOES MY BODY USUALLY GET RID OF MUCUS?

Cilia are tiny hairs that cover the cells on top of the mucus membranes in your airways. These tiny hairs transport mucus and the particles that they’ve trapped toward your throat.

 

The mucus and trapped particles either get coughed up or swallowed without you even noticing. But when that process doesn’t work, excess mucus may accumulate in your airways and you may start to cough more.
