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.

Continuing to recover from hurricane “Sandy” we saw what happens when power is temporarily interrupted.  If your lungs were to lose some power, your filtering system would become clogged with dust because with every breath you take, you breathe in dust that is laden with toxic materials.  Yet, to prevent this, your filtering system is quite elaborate:  tears, mucus and tiny hair, all play a part.

This filtering 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.  In hot weather it cools the air as it passes into you lungs.

What is “self”? (3)

The innate intelligence of the body at all times uses the immune system to survey the chemical markers of every molecule and cell in our body.  Because the marks on our body cells differ from those that brand foreign substances, the immune system can pick out intruders and avoid the reckless execution of friends.  If the system recognizes a mark as self, it will usually respect the substance; if it detects a foreign mark, it will launch an attack to destroy the invader.

Any substance that trigger such an attack is called an antigen.  Viruses, parasites, fungi and bacteria can act as antigens.  So can blood cells or tissue from another human being and altered self-components, including cancer cells or cells infected by a virus.  Even seemingly innocuous substances, such as ragweed pollen, mildew, animal hairs, or house dust, can provoke a full blown attack.
