  Immune System - NIAID Net News
The immune system is a complex of organs--highly specialized cells and even a circulatory system separate from blood vessels--all of which work together to clear infection from the body.
The organs of the immune system, positioned throughout the body, are called lymphoid organs.
The spleen, at the upper left of the abdomen, is also a staging ground and a place where immune system cells confront foreign microbes.

  The Immune System
The immune system is a complex network of organs containing cells that recognize foreign substances in the body and destroy them.
Immune responses are normally directed against the antigen that provoked them and are said to be antigen-specific.
Immunologic memory is the ability of the adaptive immune system to mount a stronger and more effective immune response against an antigen after its first encounter with that antigen, leaving the organism better able to resist it in the future.

  Immune System - MSN Encarta
Immune System, group of cells, molecules, and organs that act together to defend the body against foreign invaders that may cause disease, such as bacteria, viruses, and fungi.
Adaptive immune responses are actually reactions of the immune system to structures on the surface of the invading organism called antigens.
The ability of the immune system to mount a response to disease is dependent on many complex interactions between the components of the immune system and the antigens on the invading pathogens, or disease-causing agents.

 The Immune System
The purpose of the immune system is to keep infectious microorganisms, such as certain bacteria, viruses, and fungi, out of the body, and to destroy any infectious microorganisms that do invade the body.
The immune system is made up of a complex and vital network of cells and organs that protect the body from infection.
The organs involved with the immune system are called the lymphoid organs, which affect growth, development, and the release of lymphocytes (a certain type of white blood cell).

 Immune system supplement to boost immune system or immune system boosting
With the Thymus as the immune system's "central command", the Spleen as the "workhorse" and the Appendix and Tonsils as the "support team" all working together to produce specialized chemicals and a variety of cells that seek out and neutralize toxins, microorganisms, allergens and cellular wastes.
While using herbs to boost immune system, it is important to avoid toxic foods such as fried foods, processed foods, sugar, tobacco, alcohol, additives and similar acidic-toxic type foods, while increasing your intake of immune system booster foods including fresh fruits, raw vegetables, whole grains and similar alkaline foods that have immune system boosting functions.
Immune Booster may be used on its own or in combination with Detox, Antioxidant or Cold and Flu.

 How the immune system works
The immune system is a network of cells and organs that work together to defend the body against attacks by foreign "invaders".
At the heart of the immune system is a remarkable ability to distinguish between the body's own cells-self-and foreign cells- nonself.
Immune serum globulin or "gamma globulin" is sometime given to protect travelers to countries where hepatitis is widespread, but such "passive immunity" typically lasts only a few weeks or months.

 Immune-System-Plus
The immune system is a complex network of organs that contain cells which recognize foreign invaders in the body and destroy them.
Lymphocytes, a class of white blood cells are the principal components of the adaptive immune system.
The human immune system contains approximately one trillion T cells and one trillion B cells, located in the lymphoid organs and in the blood, plus approximately ten billion antigen-presenting cells located in the lymphoid organs.

 Colostrum, transfer factor and your immune system
You catch a cold usually because some virus or germ has entered your system and your body was unable to get rid of the germ before it multiplied and gave you clogged sinuses, sniffles and a runny nose.
Immune cells cause small blood vessels near the 'clump' of multiplying bacteria to dilate and widen.
After all, your immune system is gradually accumulating all sorts of new antibodies so that by the time you are old, your immune system would be ready to attack almost any bug that ever existed.

 Immune System
Parts of the immune system are antigen-specific (they recognize and act against particular antigens), systemic (not confined to the initial infection site, but work throughout the body), and have memory (recognize and mount an even stronger attack to the same antigen the next time).
The blood and lymph systems are intertwined throughout the body and they are responsible for transporting the agents of the immune system.
It is in the lymph nodes where antigen is usually presented to the immune system.

 The Immune System -- An Overview - The Body
The immune system is composed of many interdependent cell types that collectively protect the body from bacterial, parasitic, fungal, viral infections and from the growth of tumor cells.
The purpose of this article is to review the organs, cell types and interactions between cells of the immune system as a commentary on their importance and interdependence on the T helper subset.
An immune response is initiated when the macrophage or dendritic cells present the antigen to the appropriate B or T cells.

  Immune system - Wikipedia, the free encyclopedia
The secondary immune organs lie near all of the possible portals of entry for pathogens: adenoids, tonsils, spleen (located in the upper left of the abdomen), lymph nodes (along the lymphatic vessels and concentrated in the neck, armpits, abdomen, and groin), the Peyer's patches (lining the intestines), and the appendix.
The innate system is thought to constitute an evolutionarily older defense strategy, and is the dominant immune system found in plants, fungi, insects, and in primitive multicellular organisms.
Given that the cornerstone of the immune system is the recognition of “self” versus “non-self” the mechanisms which protect the human fetus (which is clearly, “non-self”) from attack by the immune system, are particularly interesting.

 Conditions By Organ: Immune system - WrongDiagnosis.com
Some of the general front-line immune defences are the skin and various membranes, but a variety of internal organs and cells provide very specific defences.
Failure of the entire immune system is immune deficiency such as in AIDS and primary immune deficiency (such as SCID).
Cancer can afflict immune system cells: leukemia is cancer of blood cells (usually white blood cells), multiple myeloma is cancer of plasma cells (a type of B-cell), and lymphoma is cancer of the lymph nodes; also possible is thymus cancer.

 National Psoriasis Foundation: Psoriasis and immune system involvement
For example, methotrexate (a prescription systemic medication used to treat psoriasis) binds to an enzyme involved in the rapid growth of cells that is triggered by the immune system response in psoriasis.
Psoriasis is frequently referred to as a "T-cell mediated disease." T cells are a type of immune system cell (white blood cell) that have been shown to be very important in the internal process of psoriasis.
Psoriasis research is benefiting from the fact that psoriasis is driven by the immune system and responds to drugs that suppress the body's immune response (immunosuppressive therapy).
