HSC 3537 Lecture Notes - Lecture 13: Blood Proteins, Heparin, Red Blood Cell
Document Summary
Blood: transports foods, gases, and wastes to and from the cells of the body. Blood proteins, white blood cells, and platelets. Erythrocytes: red blood cells transport nutrients and oxygen. Basophils: contain heparin (prevents clotting) and histamine (involved in allergic responses) Eosinophils: phagocytic cells involved in allergic responses and parasitic infections. Neutrophils: phagocytic cells that accumulate at sites of infection. Monocytes: phagocytic cells that become macrophages and digest bacteria and tissue debris. Lymphocytes: control the immune response; make antibodies to antigens. Maintains the proper proportion and concentration of water in the blood. Globulins: immunoglobulins (igg, iga, igm, igd, ige) Antibodies that bind to and sometimes destroy antigens or foreign substances, ie. , igg, iga. Type ab: a and b antigens and no antibodies (universal recipient) Type o: no a or b antigens and both anti-a and anti-b antibodies (universal donor) Aplastic anemia: failure of blood cell production due to aplasia or absence of cell formation of bone marrow cells.
