Blood, Lymphatic & Immune System 13&14 Flashcards
antibody (Ab)
specific protein (immunoglobulin) produced by lymphocytes in response to bacteria, viruses, or other antigens. specific to an antigen and inactivates it.
antigen
substance (usually foreign) that stimulates the production of an antibody
coagulation
blood clotting
differentiation
change in structure and function of a cell as it matures; specialization
erythroblast
immature red blood cell
erythocyte
red blood cell.
erythropoieten (EPO)
hormone secreted by the kidneys; stimulates red blood cell formation
leukocyte
white blood cell
lymphocyte
mononuclear leukocyte that produces antibodies
neutrophil
granulocytic leukocyte formed in bone marrow.
a phagocytic tissue-fighting cell AKA polymorphonuclear leukoocyte
plasma
liquid portion of blood; contains water, proteins, salts, nutrients, lipids, hormones, and vitmains
platelet
small blood fragment that collects at sites of injury to begin the clotting process
thrombocyte
platelet
hematopoiesis
hemat/o=blood -poiesis=formation
all blood cells originates as being similar and then begin the process of specializing or differentation
hemophilia
hem/o-blood
-philia= attraction to
inherited lack of clotting factors-liver fails to produce clotting factors
bone marrow biopsy
microscopic examination of a core of bone marrow removed with a needle.
complete blood count (CBC)
determination of numbers of blood cells, hemoglobin concentration, hematocrit, and red cell values– MCH, MCV, MCHC
prothrombia time (PT)
test of the ability of blood to clot
erythocyte sedimentation rate (ESR)
speed at which erythocytes settle out of plasma
organs of lymphatic system
bone marrow and blood leukocytes are produced here, of which, lymphocytes are part
Lupus
systemic lupus erythematosus (SLE) is a chronic autoimmune disorder. may affect skin, joints, kidneys, and other organs(SLE) is an autoimmune disease
sickle cell anemia
hereditary disorder of abnormal hemoglobin producing sickle-shaped erythrocytes and hemplysis
white blood cells (WBC)
number of leukocytes per cubic millimeter or microliter of blood
leukemia
increase in cancerous white blood cells (leukocytes)
multiple myeloma
malignant neoplasm of bone marrow
anemia
deficiency in erythrocytes or hemoglobin
lymphoma
malignant tumor of lymph nodes and lymph tissue.
cancer of lymph nodes
