The tonsils are masses of lymphatic tissue and produce lymphocytes that trap and kill bacteria entering the mouth and throat to gaurd the respiratory and digestive systems.
Thymus A lymphatic mass functioning in the programming of lymphocytes. It Produces and converts the B-cells into T-cells which are specialized to meet a particular enemy. The thymus produces a hormone called thymosin and acts as an incubator for the maturation of T lymphocytes. Stress shrinks the thymus.
Resides in the skull, ribs, shoulder blades, vertebrae, breastbone, and hip bones. It generates stem cells crucial to our immunity. Various stem cell types assist in regeneration and repair throughout our bodies.
Lymph is a colorless blood serum derived from plasma that has leaked from the bloodstream into the tissue spaces and is recovered by a network of tiny vessels that separate it from the bloodstream. This fluid brings with it tissue toxins, excess fluid, dead cells, and microbes, removing them from the body.
Tiny, thin-walled vessels made up of one-way valves that pump lymph fluid along by the contraction of nearby muscles during activity. Since muscle contractions serve to pump the plasma, we must exercise if we want to maintain the lymphatic highway or our immune system.
Our Immune Defense FortressOur defense system is set up like an army: protective barriers, specialised soldiers, manufacturing stations, transportation systems, storage areas and clean-up crews. The immune system's job is to defend the body. It's activated by invading organisms. Most respiratory symptoms are caused by the immune system. These symptoms are helpful, even essential, in overcoming an illness.
Protective BarriersOur skin is the outer wall of
the fortress. The eyes, nose, and mouth are protected by mucous that
captures harmful attackers. In the Nose are cilia, which are tiny hairs
that trap particles. In the stomach, intruders pass through stomach acid
that will destroy most of them.
Helpful Immune System Defense
Coughing is a natural reflex that expels disease-causing germs from the lower respiratory tract. It clears the lungs and bronchi of excess mucus, helping prevent pneumonia.
SneezingSneezing is a convulsive explosion of air from the lungs through the nose and mouth. It is a protective reflex that clears the upper airway of germs, irritants, and mucus.
FeverFever kills invading organisms and “pasteurizes” the blood. It speeds metabolism and enhances delivery of oxygen and nutrients to sites of infection. It hastens removal of cellular debris and toxins.
Cause of Poor ImmunityStress and the immune system
According to the CDC, as much as 90% of all illness can be directly tied to stress, because it breaks down the defenses of the immune system and opens the doorway to a host of injurious invaders.
- Cleaning agents
It is estimated that 85% of all debilitating diseases are closely related to toxin-related pollution present in the environment. Some include:
The Roles of AntibioticsLife-saving in some cases, but definitely overused in the U.S. Overuse produces antibiotic-resistant “superbugs,” and is a world-wide public health problem. It's effective only for bacterial infections—not viral or fungal infections. Antibiotics kill bad bacteria and good bacteria, including friendly bacteria, probiotics in the gut.
Concern: No New Antibiotic Development“Research
and development of new antibiotics isn't keeping up with development of
resistance. If we don't do something about it we'll end up with a
situation where all the old drugs have resistance and we don't have any
new ones,“ said Dr. Kathleen Holloway of the World Health
Organization. In some parts of the world there is already antibiotic
resistance to TB, Dysentery and Pneumonia.
Concern: Challenging Viruses
There is an increased concern about viral invaders, and it seems we are frequently being warned of a new ominous virus. Although new vaccines are being developed; they only target several strains of viruses and side effects are a concern
VirusesViruses need a host cell because they do not reproduce on their own. They seize control of a cell, and often the cell is destroyed during this process. Viruses include:
The Common Cold
Respiratory System Diseases
There are numerous problems and diseases. They can include colds, bronchitis, croup, sinusitis, pneumonia and influenza.
Short-lived inflammation of trachea and large and small bronchi. Caused by viral or bacterial infection. Often follows cold or flu. Coughing is persisitent in its attempt to clear the mucus. Other symptoms include hoarseness, fever, wheezing and dull chest pain.
