It helps you fight off a lot of terrible disease-causing bacteria, viruses.
The immune system is a system of many biological structures and processes within an organism that protects against disease. To function properly, an immune system must detect a wide variety of agents, known as pathogens, from viruses to parasitic worms, and distinguish them from the organism's own healthy tissue. The principle behind vaccination (also called immunization) is to introduce an antigen from a pathogen in order to stimulate the immune system and develop specific immunity against that particular pathogen without causing disease associated with that organism. Your immune system works because your body is able to recognize self and non-self.. This means that your body is able to tell if an invader (virus, bacteria, parasite, or other another person's tissues) has entered it—even if you aren't consciously aware that anything has happened.  A Discovery Health answered. Antibodies (also called immunoglobulins and gammaglobulins) are produced by white blood cells. Antibodies are Y-shaped proteins that respond to a specific antigen (bacteria, virus or toxin). Every antibody has a special section (located at the tips of the Y branches) that is sensitive to a specific antigen and can bind to it. When an antibody binds to a virus particle's outer coat or the cell wall of a bacterium it can stop the virus or bacterium's movement through cell walls. A large number of antibodies can latch on to an invader and signal the complement system that it must remove that invader. Antibodies Defined. Antibodies are proteins that are produced by the immune system to help stop harm from occurring. They are also called immunoglobulins. When an intruder, such as a virus, bacteria, or other chemical, enters the body, the immune system springs into action. Chemical signals are sent to alert all the different parts of the immune system into action. First, the B cell meets the antigen. The B cell will create the antibody protein and stick it to the antigen. Next comes the T cells that begin to destroy The body’s defense against various microorganisms that cause disease and illness is the immune system. The immune system attacks these disease causing organisms through a sequence of steps referred to as the immune response. The immune system is composed of a number of cells, tissues and organs that work in association and attacks the disease causing microorganisms and protect the human body. The cells of the immune system are the leukocytes or the white blood cells When foreign particles or antigens invade the body, the various types of immune system cells work in combination to recognize and destroy them. The B lymphocytes are triggered in the process producing antibodies, which are specialized proteins that block specific antigens. The immune system is composed of a number of cells, tissues and organs that work in association and attacks the disease causing microorganisms and protect the human body. Helper T cells activate B cells that produce antibodies. Supressor T cells slow down and stop the immune response of B and T cells, serving as an off switch for the immune system. Cytotoxic (or killer) T cells destroy body cells infected with a virus or bacteria. Antigens are chemicals on the surface of a cell. All cells have these. The immune system checks cells and identifies them as self or non-self. Antibodies are proteins produced by certain lymphocytes in response to a specific antigen. B-lymphocytes and T-lymphocytes produce the antibodies. B-lymphocytes become plasma cells which then generate antibodies. T-lymphocytes attack cells which bear antigens they recognize Antibody Function. Antibodies, or immunoglobulins, are little glycoproteins floating around in your body that help you fight off a lot of terrible disease-causing bacteria, viruses and the like. You know that much, I'm sure. Another way is by way of agglutination, which is the process whereby antibodies cause cells to clump together. Finally, antibodies can cause neutralization. This is a process whereby antibodies stick to dangerous substances so they cannot harm our body's cells. When an antigen enters the body or tries to enter the body, the immune system is triggered. Chemical signals are sent to alert all the different parts of the immune system into action. First, the B cell meets the antigen. The B cell will create the antibody protein and stick it to the antigen. Next comes the T cells that begin to destroy the antigen. Soon, the phagocytes finish off the antigen
