Breathing Brooms - The Cilia

You are certainly familiar with the clear, warm, sticky blanket of mucous that lines most of your respiratory passages. The multipurpose mucous layer protects the underlying tissues of your nasal cavities, sinuses, throat and descending bronchial passages that wend their way between your nose and your delicate deep lung tissue.

Mucous is a super “fly paper” that releases moisture into the incoming dry air while at the same time grabbing up a billion bits of airborne bouncing garbage before it finds its way into your delicate lungs. Mucous is great stuff but once it has picked up a full load of garbage, you don’t want it hanging around.

Sprouting outward from the walls of most of your respiratory tunnels are millions of microscopic hair-like projections called “cilia” that beat and sweep like tiny brooms. A healthy cilia-covered wall resembles a microscopic wheat field in a stiff breeze. These extraordinary pushy little brooms beat as many as 50,000 times per hour to push along your mucous layer.

Under ideal conditions old polluted mucous is regularly dumped out through your nose, mouth or digestive tract. At the same time new fresh clean mucous is produced by tiny goblet cells embedded in your bronchial walls. For this defense system to work effectively the mucous layer must be moist enough to be pushed along easily and the sweeping cilia must remain strong and active. Infection, smoking, lack of fluids and allergies can stun or cripple the cilia and can halt the movement of the mucous in its tracks.

Be well. Breathe beautifully.
