Immune system is a kind of defensive shield inside the body of human beings and animals that acts as a combatant against various diseases. It constantly defends animals and human beings from the development of anti bodies in the body and kills the infectious bugs. Nature has developed internal genetic protective system that ensures the health of the plants, animals, fishes, and insects as well as of human beings. When this defensive mechanism is weak, diseases of various kinds attach the body. Immune system works by differentiating between the healthy cells of body and unnecessary cells formed due to a virus contact. It kills those unwanted harmful cells from the body and prevents the formation of malignancies.
There are numerous factors that can contribute to the well being of immune system. Those factors are: the healthy diet, proper sleep, regular exercise, hygiene and mental fitness.
The mechanism of immunes can be understood as a physical blockade that protects organisms from infections and bacteria. The whole body consists of different types of protective agents that may become weak resulting in deterioration in the health of organism. Some defensive instruments are chemicals that are inside the stomach meant to prevent stomach from the germs entering through the food intake. The tears in eyes, saliva and pure milk are also anti germ chemical protections inside organisms and effectively protect against infections. Some are mechanical and biological mechanisms that lies in the blood and tissues of an organism. Such systems prevent the formation of tumors or anti germ bodies inside the bones, muscles and tissues.
The basic response of immune system to the bugs which enter the body is the course of inflammation. In this response of inflammation, the defensive immunes injure the germs. This produces the excess of blood in the tissues as the immune system inflames the outer infectious agents.
Secondly the immune system also competes with the outer germs by attacking the location of infection. The proteins in the immune friendly fighting agents help kill the pathogens produced by the germs inside human body. The immune system also fights the disease with the formation of cellular shields. In this regard, it uses white blood cells as innate eradicator cells. When these immune mechanisms inside an organism are strong they remain fighting against the infections and save the organism from the poor health.
Due to the weakness of the immune system, the chances of receiving the swine flu increases for both human beings and pigs. All other viral infection also attack due to deficiency in the immune system. The individuals, who have weak immune systems may suffer from lifelong chronic and life intimidating infections in their body. The transfer of swine flue may also be regarded to the easily broken defense mechanisms in pigs. The same can be the reason for human beings getting swine infection from pigs as well as from each other. The natural flu and zoonotic swine flu are the viral infections found spreading due to the same reason.
For such importance the doctors suggest the patients to take immune strengthening food and adopt measures that reduce chances of weakening body’s defensive mechanism.
