The Immune System is a system of institutions responsible for defending the body. The immune system consists of many different organs and tissues. The most important of these is the bone marrow, and thymus gland. These are created and developed specific cells immune system. Subsidiary organs of the immune system are tonsils The Spleen, The lymph and Peyer plates.
The Immune System of Your body has several defense mechanisms which enable to attack and destroy unwanted and potentially harmful microscopic invaders.
The body's defense mechanisms are divided into two categories. In non-specific mechanisms and specific mechanisms. In non-specific mechanisms have the basic reaction of any kind infections? This mechanism consists of four types of defensive barriers:
- Anatomic barriers (skin, Mucous membranes)
- Physiological barriers (temperature, pH, strain)
- Mechanisms of endocytosis and phagocytosis
- Inflammatory response (blood vessel dilation, increased permeability of capillaries in tissue)
The specific mechanism characterized by memory and recognition ability of harmless cells from damaged or mutated cells. The first defense line of defense organization is achieved through Skin and investment institutions which communicate with the outside environment. These containing chemicals that break down and remove unwanted organizations. If an organization somehow managed to escape from the defensive layer of the skin, your immune system then mobilizes a variety of other mechanisms defense.
A few cells surrounding agencies while other cells, usually white blood cells called neutrophils , Leave the blood vessels and penetrate the area of injury or contamination.
Now, other cells that destroy bacterial organisms, hereinafter macrophages, traveling to injured area.
Expand the "tentacles" of which close and trap the body bursts. The macrophages then with powerful chemicals destroy the bacteria or absorb it completely. The macrophages and skin with other components of immune action, such as antibodies, provide a multilateral defense and protection against infections.
The immune system is one of the major systems of the body that determines human health. The integrity of the immune system is affected mainly by aging, hormonal disorders, stress and implementation of a non- balanced diet.
When the immune system is weak, then we become more vulnerable to colds, flu and other more serious situations.
It has been shown that some nutrients found in foods and we consume daily is necessary to strengthen the natural defenses body, providing protection from diseases, infections and allergies. As winter comes, you should adjust your diet in such how to stay healthy and strengthen our immune system. Children and elderly are particularly vulnerable groups in diseases and are essential to have a proper and balanced diet.
Vitamin C is very important for our immune system. Contribute increased production of white blood cells and adequate levels of interferon, protein with a key role in the prevention of the proliferation of viruses. It also helps to maintain good condition of blood vessels, facilitate the absorption of iron from the body and helps faster recovery of health. However, a recent review of 30 clinical studies showed that supplementation of vitamin C can play a positive role in reducing the duration of symptoms of joint cold, but not to similar flu.
