What is the immune system?
Without that, we would all be forced to live in a sterile environment, never touch each other, never feel spring breeze, never taste the rain. The immune system is a complex operation in our bodies that keeps us healthy and without disease.
Not few systems in nature are as complicated as the human immune system. It exists and works in accordance with each other system in the body. When it works, people remain healthy. When the disorders, there are terrible things.
The main component of the immune system is the lymphatic system. Small organs called lymph nodes help wear lymphatic fluid throughout the body. These nodes are located most prominently in the throat, armpits and groin. The lymphatic fluid contains lymphocytes and other white blood cells and circulates throughout the body.
White blood cells are the main combat soldiers in the body's immune system. They destroy foreign or sick cells in an effort to clean them from the body. That's why a raised wpleti of HITE blood cells is often a sign of infection. The worse the infection, the more white blood cells that the body sends to fight it.
white and red blood cells are produced in spongy tissue called bone marrow. This substance -rich substance is essential for a properly functioning immune system. Leukemia, bone marrow cancer, causes significantly increased production of abnormal white blood cells and allows the release of immature red blood cells into the body. Other features such as low nose and mucus lining help bacteria to capture bacteria before they get into the bloodstream to cause infection.
B cells and t cells are the main types of lymphocytes that attack foreign cells. B cells produce antibodies adapted to different cells at the command of T cells, regulators of the body's immune response. T cells also destroy sick cells.
Many diseases that borne humanity are the result of insufficient immunity or inappropriate immune response. For exampleLad cold is caused by a virus. The body does not recognize some viruses as harmful, so the reaction of t cells is "pass, friend" and begins sneezing.
allergies are examples of inappropriate immune response. The body is hyper-vigilant and sees the evil pollen as a dangerous attacker instead of a harmless yellow powder. Other diseases such as diabetes and AIDS suppress the immune system and reduce the body's ability to fight infection.
vaccines are necessary to discourage some diseases to help the body. The body is injected with a weakened or dead form of virus or bacteria and produces suitable antibodies, which provides complete protection against the form of disease full force. That is why such disorders such as diphocks, mumps, tetanus and pertussis are rarely visible today. Children were vaccinated against them and the immunystem E is in alert. Vaccines were also helpful in the eradication of the sea, such as smallpox and polio.
Antibiotics also help combat disease in the body, but doctors are more careful in prescribedThe broad -spectrum diversity, because certain bacteria are beginning to show resistance. The next time you hug a loved one or feel roses, thank you to your immune system.
