The immune system .. How does it work and how can it be strengthened?

Yemen's news in its fight against pathogens and viruses The body is doing its best to stay healthy and stay away from anything that harms it. However, it can happen that viruses, etc. If this happens frequently, it indicates the weakness of the immune system. But what is the immune system?

To answer this question, Professor Ulrich Fulch of Germany has stated that the immune system is a very complex system that spreads throughout the body and is an interaction between cells, tissues and chemical environments of all kinds.

Immunity starts with the skin

The work of the immune system begins with the skin, which is a protective barrier against germs attacks and contains a slightly acidic pH that prevents the infiltration of bacteria and other similar organisms into the body. Membranes, nasal hair and bronchi prevent the passage of bacteria in the body.

If bacteria can enter the body through food, it is the saliva that tries to fight it. In case of failure, gastric acid takes over.

Natural and specialized defense

There is also what is called the "natural defense", which consists of body cells that devour everything that seems strange to the body. These so-called macrophages are called "placenta" or only cells.

If this natural defense fails to eliminate the pathogens, the body then activates the specialized defense, called B-cells and T-cells, which belong to the white blood cell group. These cells develop antibodies that particularly affect known pathogens in the body.

The immune system has a similar memory and remembers that it had already been treated with these germs: if the body has to face a new attack by the same cause of the disease, the specialized immune system recognizes it and l & # 39; 39, eliminates quickly.

The person who has scarlet fever will no longer contract the disease, unlike the flu, because its composition continuously changes in composition, so you usually have the flu more than once in your life.

Causes of immunodeficiency

Infections occur when the immune system weakens. This weakness is due to several reasons, including lack of sleep and constant psychological stress, as well as chronic diseases such as diabetes and AIDS.

German pharmaceuticals Ursula Zellerberg pointed out that drugs can weaken the immune system. Antibiotics can only be used under the supervision of a doctor because they destroy not only the harmful organisms, but also the beneficial bacteria, which the intestines especially need to carry out digestion.

Zellerberg said that the immune system can be strengthened with simple weapons of healthy and balanced diet, in addition to the practice of sports and outdoor activities, taking into account the fact of washing hands regularly. A good weapon is also getting enough sleep at night, while relaxation techniques such as yoga and meditation help to combat psychological stress.
