Citizens of the body?

We live in a world dense with microbes:  bacteria, virus and fungi abound in the air, water, and soil, and on the living things around us.  Most of these organisms have little interest in the human species.  Yet a specialized few find the human body an inviting habitat:  warm, protected, and well stocked with nutrients.

Some settle in the nose and ears, some on the skin and in the intestinal tract.



2 lungs to breathe? (3)

If the air you breathe reached your lungs without being filtered, you wouldn’t live very long.  You lungs would quickly become clogged with dust since with every breath you take, you breathe in dust.  And that dust is also laden with toxic materials.  Yet, to prevent this, you also possess a marvelous filtering system in which tears, mucus and tiny hairs play a part.

This system also prevents the lungs from being scorched by hot air, or frozen by cold air.  In cold weather the innate intelligence of the body warm the air with that system.  In hot weather the innate intelligence of the body cools the air as it passes into your lungs.



2 lungs to breathe?

Every day your body uses about 90 gallons of pure oxygen.  To separate this gas from the air, the innate intelligence of the body uses your lungs.

The lungs contain 500,000,000 tiny air sacs with a surface area of 50 to 60 square MILES!  The walls of the sacs and of the blood vessels that wind around and around each one are one cell thick.  Molecules of oxygen leave the air in the sacs and pass right through these 2 one-cell walls into your blood.

At the same time, molecules of carbon dioxide gas (which your body must get rid of) go from your blood into the air sacs and are exhaled with your breath.  This process is called diffusion.



Trappers or garbage collectors? (2)

WOW!  2 blogs in 2 days.  What’s up with that?  Yesterday at the office I learned from Robert that the transformer I am using to demonstrate your growing into a life of maximum performance is vintage.  It’s the first generation transformer called:  MEGATRON.  You can find them on e-bay for a hefty price tag.  Well, Robert sold it to me for a mere fraction of the full value.  Thank you Robert and for those of you who have not yet seen me in action with it, please ask me for a demonstration.

Also a simple reminder that my next chiropractic event at Michael’s restaurant is next tuesday at 7pm for a complimentary italian dinner and a power point presentation about my objective as an unadulterated straight chiropractor exclusively.  Please bring a friend or two that you care about and that you have always wanted to share with them the value of our service at Lessard Chiropractic Centre.  Call Tara and let her know how many people you will bring so she can advise the chef at Michael’s.

Pursuant yesterday’s blog, during the course of a day in a city like Philadelphia, we inhale 17000 pints of air.  That air contains some 20 billions particles of foreign material, including dirt, dust and chemicals, most of which never make it to the lungs.

Airborne matter that enters the nose must pass through a trap of stiff nostril hairs that catches many of the larger particles.  Just past this trap, the direction of the airstream shifts abruptly with the curve of the bones in the nasal passage, forcing some of the larger particles to collide with the wall of the pharynx.  Here, the innate intelligence of the body uses tonsils and adenoids (strategically placed tissues containing agents of the immune system) to trap foreign material and see to its destruction.

Amazing isn’t it?


Is that a big eater? (2)

Unlike neutrophils, which lives for only a few days, mature macrophages live in the body’s tissues for months, perhaps even years.  Some act as janitors, sweeping up dirt, damaged tissue, and aged cells.  Each day, the macrophages in a single human body consume more than 300 billions dead or dying red blood cells.

In the lungs, macrophages continuously clean the surfaces of the air sacs, mopping up the bits and pieces matter that find their way past the nostril hairs and cilia of the respiratory tract.  As long as they do not have to cope with additional smoke pollution, macrophages can eventually restore the lung’s normal appearance.

Therefore, it is never too late to quit smoking.
