Some cells in the trachea and large airways secret a sticky liquid called mucus.

Mucus traps particles of dirt or bacteria that are breathed in . The cilia beat

forwards and backwards , sweeping the mucus and trapped particles out towards

the mouth.

那請問mucus係咪姐係等於淡?

更新1:

So is sputum produced by the trachea and large airways?

✔ 最佳答案

mucus is not totally equal to sputum since most mucus is swallowed and only for those undesirably coughed out we will refer to as sputum.
