The soul is divided into a rational part and an irrational part. The rational part can be further divided into a contemplative part, which studies the invariable truths of science and mathematics, and a calculative part, which deals with the practical matters of human life.
Immunoglobulin A (IgA, also referred to as sIgA) is an antibody that plays a critical role in mucosal immunity.More IgA is produced in mucosal linings than all other types of antibody combined; between three and five grams are secreted into the intestinal lumen each day.This accumulates up to 15% of the total immunoglobulin produced in the entire body.he high prevalence of IgA in mucosal areas is a result of a cooperation between plasma cells that produce polymeric IgA (pIgA), and mucosal epithelial cells that express an immunoglobulin receptor called the polymeric Ig receptor (pIgR).
Selective IgA Deficiency is defined as a primary immunodeficiency characterized by an undetectable level of immunoglobulin A (IgA) in the blood and secretions but no other immunoglobulin deficiencies. There are five types (classes) of immunoglobulins or antibodies in the blood: IgG, IgA, IgM, IgD and IgE.IgG is present in the largest amount, followed by IgM and IgA. IgD is much lower, and IgE is present in only minute amounts. IgM and IgG mainly protect us from infections inside our body tissues, organs and blood.here are five types (classes) of immunoglobulins or antibodies in the blood: IgG, IgA, IgM, IgD and IgE.
