Rh Blood Group
Category of blood type. When the Rh factor is present on the surface of RBCs, the blood is Rh positive. W/O the Rh factor, the blood is Rh negative.
304
Aggregation
Process of platelets sticking to a damaged blood vessel and forming clots.
305
Clotting Factors
A series of 12 substances (factors) that are released from platelets or injured tissue or are produced by the liver. They activate each other in a series of steps that form fibrin strands that trap RBCs and from a blood clot.
306
Fibrin
Strands formed by the activation of clotting factors. Fibrin traps RBCs to form a blood clot.
307
Thrombus
Blood clot
308
Coagulation
Forming of a blood clot by platelets, RBCs and clotting factors.
309
Hemeostastis
The cessation of bleeding.
310
Lymphatic Vessles
Vessels that begin as capillaries, carry lymph, continue through lymph nodes, and empty into the right lymphatic duct or the thoracic duct.
311
Lymph
Fluid that flows through lymphatic system
312
Lymph Nodes
Small, encapsulated pieces of lymphoid tissue located along lymphatic vessels. Aka lymph glands.
313
Lymphoid Tissues
Contain lymphocytes that are active in the immune system. Tonsils, Adenoids, Appendix
314
Thymus
Lymphoid organ located within the mediastinum. As an endocrine gland, it secretes thymosins.
315
Spleen
Lymphoid organ located in the abdominal cavity posterior to the stomach. The spleen destroys old erythrocytes, breaking their hemoglobin into heme and globin chains. Also acts as a storage are for whole blood. Contains B and T cell lymphocytes.
316
Blood Dyscrasia
Any disease condition involving blood cells.
317
Hemorrhage
Loss of a large amount of blood, externally or internally. Injury to an artery causes a forceful spurting of a large amount of bright red blood.
318
Pancytopenia
Decreased numbers of all types of blood cells due to failure of the bone marrow to produce stem cells.
319
Septicemia
Severe bacterial infection of the tissues that spreads to the blood.
320
Abnormal Red Blood Cell Morphology
Erythrocytes have an abnormal size or shape.
321
Anisocytosis
Erythrocytes that are either too large (macrocyte) or too small (microcyte).
322
Poikilocytosis
Erythrocytes that vary in shape, for example sickle cell
323
Anemia
Deficiency in erythrocytes of hemoglobin.
324
Aplastic Anemia
Failure of blood cell production due to absence of development of bone marrow cells.
325
Hemolytic Anemia
Reduction in red cell due to excessive destruction. May be congenital or autoimmune in origin.
326
Pernicious Anemia
Lack of mature RBC due to inability to absorb vitamin B12
327
Iron Deficiency Anemia
Caused by a deficiency of iron in the diet or blood loss.
328
Hemochromatosis
Excessive deposits of iron throughout the body. Hepatomegaly. Pigmented skin. Diabetes and cardiac failure may occur. Usually seen in men over 40 years of age.
329
Folic Acid Deficiency Anemia
Caused by deficiency of folic acid in the diet. Commonly seen in people who are malnourished or who have malabsorption diseases.
330
Sickle Cell Anemia
Caused by an inherited genetic abnormality of an amino acid in hemoglobin. Affects the spleen.
331
Polycythemia Vera
General increase in RBC. Blood is very viscous. Treatment by phlebotomy.
332
Thalassemia
Inherited genetic abnormality that affects person living in or who are ancesters from the Mediterranean Sea Area. Cooley's Anemia.
333
Hemolysis
Destruction of RBCs
334
Acquired Immunodeficiency Syndrome (AIDS)
Severe infection caused by the human immunodeficiency virus (HIV), a retrovirus.
335
Leukemia
Cancer of the leukocytes. Excessive numbers of leukocytes crowd out other cells in the bone marrow. There is anemia, easy bruising and hemorrhages (too many thrombocytes), fever, and susceptibility to infection (immature leukocytes)
336
Aculte Myelogenous Leukemia (AML)
Immature myeloblasts predominate.
337
Acute Lymphocytic Leukemia (ALL)
Immature lymphocytes predominate, seen most often in children and adolescents.
338
Chronic Myelogenous Leukemia (CML)
Both mature and immature granulocytes are present.
339
Chronic Lymphocytic Leukemia (CLL)
Abnormal numbers of mature lymphocytes. Seen mostly in elderly and follow a slow course.
340
Mononucleosis
An infectious disease with an increase of lymphocytes and enlarged cervical lymph nodes. Epstein-Barr virus. Hepatomegaly. Splenomegaly
341
Multiple Myeloma
Malignant tumor of bone marrow. Progressive tumor of antibody producing cells that invade bone marrow and destroy bone.
342
Lymphedema
Generalized swelling of an arm or leg that occurs when a chain of lymph nodes have been removed.
343
Lymphadenopathy
Enlarged lymph nodes. Lymph nodes may be palpated.
344
Thrombocytopenia
Deficiency in the number of thrombocytes due to exposure to radiation, chemicals, or drugs that damage stem cells in the bone marrow.
345
Coagulopathy
Any disease that affects the ability of blood to clot normally.
346
Disseminated Intravascular Coagulation (DIC)
Sever clotting disorder in which multiple small thrombi are formed throughout the body. Triggered by sever injuries, burns, cancer or infections.
347
Mono
caused by epstin barre virus
348
what does shilling test detect?
Pernicious anemia (vit b12 deficiency)
