The immune system: how it works and how to improve

Leukocyte between erythrocytes

The immune system is one of the keys to a good quality of life as we defend our illnesses and many pathogens. He is responsible for preventing the entry into our body of unwanted and dangerous pathogens (viruses, bacteria, allergens, etc.).. When one of these enemies enters our body, the immune system will alert and choose the most appropriate defense strategy as one of the two possible situations that may arise.

It may have two different situations

1 - That our enemy (bacteria, viruses, etc..), And has come before in our body. Then the defense system has already stored all information about who he is, where it tends to attack and how to end it, because the immune system saves and stores all information in the body attacks received through the memory cells and therefore, use this information for future attacks.

2 - The pathogen is unknown to the immune system. Then the immune system will attack with all their artillery, but in a less organized and knows nothing of the pathogen and not have the information for proper disposal. In this case, our body will have more intense healing reactions.

Structure and functioning of the immune system

To understand simply, our body is like a walled city, with its watchtowers and guards. The enemy or pathogen must first pass through the wall to enter the city.

The skin and mucosa of the mouth and throat

The skin is the first barrier that bacteria and pathogens have to cross, and not have it all easy, because thanks to the daily skin peeling our body is clear of all microbes that adhere to our skin. If no injury (gaps in the wall) there is usually no problems.

However, he may think you can be vulnerable at the mouth and nose. You're right, they are more vulnerable than the skin but we are not helpless. The mucosa of the mouth and throat are protective substances that defend us. Among these substances is lysozyme. This natural substance destroys the cell membrane of microbes. This substance is found in sweat, saliva and tears and explains why animals lick their wounds as protection.

Suppose that the germ gets past this first barrier or wall and enter the city, our body due to injury. Then our army of specialized cells are put into action: the white blood cells. Here we must distinguish between three types of cells with different specialized functions: monocytes, neutrophils and lymphocytes.


If monocytes receive notice that an area is inflamed by the entry of an infectious agent will leave the bloodstream and lead to tissue. They devour the infecting pathogen. Monocytes secrete a substance called cytokines, which prepare the body to fight infection, for example cause fever. Fever as we have already spoken on other occasions SaludBio is a defense mechanism that warns us that there is a problem, but that facilitates healing by destroying the microbes or bacteria that will not withstand the temperature rise experienced by our body.


Neutrophils as monocytes are directed to the affected area and help monocytes to kill bacteria. When this die fighting bacteria and neutrophils, the body expels in the form of pus. So the pus is another type of defense against infection. Once produced the struggle will have been a waste that lymphocytes need to 'analyze' or 'collect' to alert the invader.


Lymphocytes, therefore, are the special unit anti-infective, develop antibodies, substances that combine specifically with a particular piece of the microbe.

Two groups of lymphocytes, with different purposes. The first constituent B cells, which release antibodies in the blood produced. It is said that B cells are the arm of the immune response and attack the enemy with extreme precision. These "look" the microbe that recognize and, like arrows, attack him in any vital part. The second team is made up of primary lymphocytes T cells, which are anchored on the surface of the antibodies that are recognized to use against the enemy in hand to hand combat, so to speak.

But our immune system is even more complicated since a subset of T cells, helper T cells help B cells to produce more antibodies and seem to "communicate" with each other, producing an exchange of information of the infectious agent.

They are also natural killer cells, while not produce antibodies, they are ready to kill any cell that has become "strange" as a result of infection.

Do not forget that this process will be etched in the memory immune lymphocytes, so if it comes up again at another time enemy, our immune system will already have the antibodies needed to kill the enemy without hesitation.

Remember, finally, that macrophages, as well as initiate the process of defense, play the role of sweepers in the city, because they remain in the affected area by reducing inflammation and cleaning the affected area of ​​cell fragments, dead cells and other waste. No doubt a marvel of design.

What if your immune system is weak?

Today almost no one has the immune system by 100%. The bad food, snuff, pollution, the few hours of rest at night and a negative mental attitude are the main causes of the weakening of our immune system. And if our defenses are not at full capacity we feel weak, lethargic, low energy and depressed, so we will be more likely to be invaded by viruses, bacteria or harmful microbes. On the other hand, drugs and antibiotics are usually taken so far to help us improve, weaken our immune system.

This situation, it is often difficult to solve, and how much we can hope for is to relieve symptoms.

How to improve our immune system

1 - First of all improve our diet, good nutrition is one of the best ways to have a strong immune system and be sure to stay well hydrated with water as pure as possible.

2 - Having a positive mental attitude is key to improving our immune system. Think positively, have an attitude of joy to life is very important not to depress our immune system.

3 - Exercise keeps us young and strong.

4 - Brushing dry skin. In the morning before the shower with a rope or a glove brush is given by rubbing the whole body (without injury) to accelerate the scaling of the skin. It will also improve blood circulation to the skin area and best meet their duties.

5 - The practice of therapies such as massage and relaxation are also helpful.

6 - Nutritional supplements.
All these are good tools to improve the strength of the immune system, but sometimes not enough. The passage of years has caused damage and recover the lost is not so simple.

Many companies in the nutritional supplementation looking for ways to find a way to strengthen our immune system with nutritional supplements. Some of these are:-Strength Imun Lamberts house or simple vitamin C.

Recently, much importance is being given to the transfer factors. These are molecules obtained from a dialyzable leukocyte extract that increase the responsiveness of our immune system. Therefore, as we see, we have tools at our disposal to improve our immune system.

But to conclude, do not you think that the best way to have a healthy immune system is complex and caring for this wonderful gift that our Creator endowed human beings for their protection?
