What is the function of cilia and mucus in the trachea, bronchi, and bronchioles?

Answer 1

Cilia which are hairs inside the respiratory system are like air filters. Mucus, however, traps smaller particles like pollen and smoke.

The cilia give mucus movement so that it can be expectorated and catch dust particles that are inhaled in the air.

Answer 2

The function of cilia and mucus in the trachea, bronchi, and bronchioles is to trap and remove debris, dust, bacteria, and other foreign particles from the respiratory tract. Cilia beat in a coordinated manner to move the mucus and trapped particles upward towards the throat, where they can be swallowed or expelled by coughing. This process helps to protect the lungs from infections and maintain respiratory health.
