|
antibody (Ab) |
protective protein produced by B lymphocytes in response to the presence of foreign substance called antigen
aka immunoglobulins (Igs) |
|
|
antigen |
substance, recognized as harmful to the host, that stimulates formation of antibodies in an immunocompetent individual |
|
|
bile pigment |
substance derived from the breakdown of hemoglobin and excreted by the liver |
|
|
cytokine |
chemical substance produced by certain cells that initiates, inhibits, increases, or decreases activity in other cells |
|
|
immunocompetent |
ability to develop an immune response or recognize antigens and respond to them |
|
|
natural killer cells (NK) |
specialized lymphocytes that kill abnormal cells by releasing chemicals that destroy the cell membrane, causing it's intercellular fluids to leak out |
|
|
hematopoiesis hemopoiesis
|
the development of blood cells to their mature form |
|
|
basophils (WBC, granulocyte) |
contain granules that stain dark purple releases histamines and heparin |
|
|
agranulocytes |
arise in bone marrow from stem cells in lymph tissue, they play an integral part in the immune system, mononucleocytes |
|
|
monocytes |
after a brief stay in vascular system, enter tissue spaces and become highly phagocytic macrophages |
|
|
macrophages |
consume large #s of pathogens, including bacteria and viruses. after they engulf a pathogen, they process it in such a way that the highley specific antigenic properties of the pathogen are placed on the cell surface of the macrophage . Thus the macrophage becomes an antigen-presenting cell (APC) |
|
|
antigen-presenting cell (APC) |
the APC awaits an encounter with a lymphocyte capable of responding to (matching) that specific antigen, then the antigen is destroyed. |
|
|
sider/o |
iron |
|
|
-blast |
embryonic cell |
|
|
-globin |
protein |
|
|
-phil |
atraction for |
|
|
anemia |
a deficiency of erythrocytes or hemoglobin in the blood; it is not a disease but a symptom of other illness. |
|
|
hemolytic anemia |
excessive blood cell destruction |
|
|
aplastic anemia |
decreased blood formation within bone marrow |
|
|
sickle cell anemia |
affects only those who have inherited the trait from both parents. If the trait is inherited from only one parent, the offspring will be a carrier but will but will not have the disorder. Treatment is designed to control or limit the number of crisis. Folic acid is commonly recomended. |
