Describe the location and importance of cilia and mucus in the respiratory system

Answer and Explanation:

Cilia:

The cilia are a series of short and numerous mobile extensions of the plasma membrane that line the cell surface of some eukaryotic organisms. The cilia perform several important functions thanks to their rhythmic movements such as, for example, protection against the attack of microorganisms in the respiratory tract by allowing the expulsion of accumulated particles in the mucosa, such as dust.

Mucus:

Mucus is a secretion that lines the mucous membranes of the body. It is a viscous colloid that contains antiseptic enzymes and immunoglobulins. The mucus is produced by cup cells in the mucous membranes that cover the surfaces of the membranes. It is composed of mucins and inorganic salts suspended in water. In the respiratory system, mucus traps small particles such as bacteria and dust, helping to prevent them from entering the body; This occurs, especially in the nose. The mucus helps in protecting the lungs, trapping foreign particles that enter the nose during normal breathing.
