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).
However, some people who have IgA deficiency experience recurrent respiratory tract infections, asthma, sinus infections, allergies and diarrhea. Selective IgA deficiency may also be found with autoimmune disease, in which your immune system attacks particular organs or tissues in your own body. Common autoimmune conditions found with IgA deficiency include rheumatoid arthritis, lupus and celiac disease.
