Data from 2006 show that space heating accounts for the greatest energy usage in the residential sector, with the rest devoted, in decreasing proportions, to appliances, water heating, and air-conditioning. At 7%, electronics usage surpasses washers/dryers and dishwashers, cooking, and computers in energy use.
1 The white blood cells produce an antibody specific to that antigen. 2  This is called sensitization.. 3  The job of the antibodies is to help white blood cells detect and destroy substances that cause disease and sickness.llergic Reaction Causes. Almost anything can trigger an allergic reaction. 1  The body's immune system involves the white blood cells, which produce antibodies. 2  When the body is exposed to an antigen (a foreign body such as pollen that can trigger an immune response), a complex set of reactions begins.
These antibodies travel to cells that release chemicals, causing an allergic reaction. This reaction usually causes symptoms in the nose, lungs, throat, sinuses, ears, lining of the stomach or on the skin. Each type of IgE has specific radar for each type of allergen. That's why some people are only allergic to cat dander (they only have the IgE antibodies specific to cat dander); while others have allergic reactions to multiple allergens because they have many more types of IgE antibodies.
