The Immune System

Your immune system is extremely complex and comprises of a collection of organs, glands, cells and proteins to protect and defend the body from potential harming infections, parasites, bacteria, viruses, fungi, allergies and cancers. When under attack your body needs to act quickly to protect itself with a number of systems each backing up the other.

The Innate Immunity System2ndimmune

The Innate Immunity System is your first line of defence and these external barriers are your emergency team to give a quick response to any attack.

  • Eyes – Tears contain an enzyme Lysozyme to  destroy away microorganisms and destroy bacteria.
  • Nose – Hairs in the nose prevent entry of microorganisms and dust assisted by sneezing.
  • Mouth – Saliva also contains Lysozyme to destroy bacteria.
  • Respiratory Tract – Mucus is secreted by cells lining the throat, windpipe and bronchi tubes and carried away by hairs or destroyed by white cells. Coughing helps to expel other microorganisms.
  • Stomach & Intestines – Stomach acid destroys most of the majority of bacteria and the intestines provide further backup.
  • Genito-Urinary system – The vagina and urethra contain commensals a bacteria to help protect from infection.
  • Skin – Unbroken skin provides an effective barrier against any infection. The sebaceous glands secrete chemicals that are highly toxic to kill bacteria.

The Adaptive Immune System

The Adaptive Immunity System is your second line of defence and its function is to identify, produce and destroy invading organisms or tumour cells that have bypassed the Innate system. Your body firsts identifies any potential threat and treats this as an antigen – a protein that is foreign. Antibodies are then manufactured by cells called lymphocytes and sent out to bombard and destroy any potential threat by multiplying and attacking.

The Lymphatic system has the job of draining away lymph from all over the body carrying bacteria and foreign particles back into the bloodstream in defence against major infection and cancer.  This system also involves the tonsils and adenoids, lymph and lymph nodes.  When these all become sore and swollen then your body is fighting infection.  The tonsils and adenoids reach their maturity when you are about 7 or 8 years old. After this time they should diminish in size and this is why it is important to realise that these are doing such an important job.  In many countries now the medical profession have just realised the importance of these glands and are very rarely removing them and if they do they wait until you reach your full maturity. Tonsils hold the memory cells for T-lymphocytes that have been activated before and the key to fighting infection in the future.  Building up the immune system with Vitamin C and other antioxidants is the best thing to do instead of removing the tonsils and adenoids.

The Thymus gland sits about 4 cm’s below the Thyroid gland and should be slightly raised. The larger the gland the healthier you are as this produces T-lymphocytes that support the immune system. The thymus does not like vaccinations or stress and diminishes and shrinks and cannot produce tlymphocytes.

The Appendix which sits at the front of the colon contains a large amount of lymphoid tissue which provides a defence against local infection.

The Spleen controls the quality of circulatory red blood cells and removes and destroys worn out red blood cells to aid the immune system. In the fetus, the spleen produces red blood cells but after birth this function is taken over the bone marrow.


The whole immune system needs an adequate healthy diet.
