NUR 3125 Lecture Notes - Lecture 9: Immune Thrombocytopenic Purpura, White Blood Cell, Progenitor Cell
Document Summary
55% to 60% of the blood volume. The majority plasma proteins are synthesized in the liver. Albumins: function as carriers/control plasma colloid oncotic pressure. Defend the body against infection and remove debris. Granulocytes (neutrophils, eosinophils, mast cells, basophils) are all phagocytes. Agranulocytes: monocytes and macrophages are phagocytes; lymphocytes are immunocytes. Contain enzymes capable of killing microoganisms and catabolizing debris ingested during phagocytosis. Powerful biochemical mediators with inflammatory and immune function, released in response to specific stimuli. Capable of ameboid movement-migrate through vessel walls (diapedesis), then to sites where action is needed. Migrate out of capillaries into the inflamed site where they ingest and destroy microoganisms and debris. Dead neutrophils release digestive enzymes which dissolve cellular debris and prepare for healing. Bands are immature neutrophils and numbers increase during inflammation. Induced by ige mediated hypersensitivity reactions to attack parasites. Contain a variety of enzymes to help control inflammatory processes. Elevated during type 1 hypersensitivity, allergic reactions, asthma.
