Scientists give direct links between the immune system and aging. People who exceed the age of 70-80 years have an immune system that works perfectly. But what is the immune system and what function does it have in the human body?
The immune system
The fundamental quality of the immune system is the ability to recognize any alien in the human body. Whether it is a bacteria circulating in the blood of a virus hidden in a tissue or a diseased cell, the immune system will look, will find and will destroy. The immune system has a memory “vision”; recognize chemical characteristics of foreign proteins. An antigen is a substance that provokes an immune response to a virus, bacterium, fungus, cancer cells, and many others. The organs of the immune system are the lymphoid organs because they are dealing with the formation and development of white blood cells, of which the most important are lymphocytes which are the first line of defense.
Basics of the immune system are:
- Spine marrow
- Lymphatic nodes
Tissue located in the small intestine. The entire immune system consists of lymph nodes, which are small structures (like grain bean) spread throughout the body. Lymphatic nodes are found in the abdomen, armpits, and neck. The role is to centralize the storage of immune cells and the remains of dead organisms. The immune system is a network, as well as blood vessels. This network contains lymph which is a clear fluid, pale yellow, which provides a metabolic exchange in the tissues and cells. Lymph cleanses body tissues and seeps through the permeable thin walls of lymph vessels.
They bear the brunt of the immune system. They are divided into two types, lymphocytes T and B. All formed in the bone marrow. Some reach the thymus; here multiply and mature. Their role is productions of antibodies which can be described as “specific chemical bullets” fatal to any bacteria. They are the so-called “killer cells”. They act alone. Phagocytes, a group of killer cells, absorb and digest foreign particles or microorganisms.
Phagocytes can be:
- Macrophage (“hidden” in the tissues)
- Monocytes (“patrolling” circulating in the blood).
Weapons immune cells
Most immune cells use chemicals that attack invading organisms, a huge variety (many “enemies”). Weapon produced is specific to each invader, each invader leaving a “specific chemical fingerprint”; defense cells produce an antidote (million chemical variations). B cells release a lot of new cells called plasma. Each is a “chemical factory” – antibodies; released into the blood, some destroy invaders, others determine the surface transformation “intruder” T cells do not secrete antibodies; they are supervising immune system called B cells arsenal is represented by interferon, interleukin, and many other chemicals. The human body goes through different stages of life, is exposed to a huge number of conditions that, if meta deficient immune system, attacking and causing imbalances as health problems. A health problem in young leaves traces on the immune system. Years pass and immune deficiencies occur, so it must be protected from youth and permanently. Immunodeficiency association with cancer has already been made. The best-known consequence of the decline of the immune system with age, thyme function is impaired, which is subject to hormonal control, and it is regulated by the brain. The important role of the thymus is underlined by the fact that immunological deficiencies are directly proportional to the decline of the functions performed by T cells (thymus-dependent). The role of T cells in the immune system extraordinarily is to stimulate the immune response. The weight of the thymus decreases with age and it starts at 20 years, and in old age only if we find it. It revealed a direct correspondence between CoQ deficiency and reduced thymus. That is why Q10 is required for the administration of youth. If we add Omega 3 and antioxidants like beta-carotene knowns, vitamin E, trace elements Se and Zn, we see that arsenal is extremely helpful antioxidant health preservation. Worth said that sea buckthorn oil, its composition, has virtually all “package of antioxidants” Also Spirulina has all the B-complex and folic acid, with a decisive role in maintaining youth. Spirulina is indispensable for vegetarians, the only plant with a high content of vitamin B12. This is why natural products, their extracts, are becoming increasingly recognized for maintaining health unaltered. That is why immunity, basic health is closely linked to the need for these cell protection products – antioxidants. For these reasons immunity should not be something abstract but concrete, measurable. This is achieved by what we eat and be understood not in terms of “more and better” but “varied and diversified and processed or no”.
