Pathology – Blood clotting, White and Red blood cells, Bone marrow.
| Question | Answer |
|---|---|
| Hemophilia: | Excessive bleeding caused by hereditary lack of blood clotting factors (factor VIII orIX) necessary for blood clotting. |
| Purpura: | Multiple pinpoint hemorrhages and accumulation of blood under the skin. ((Hemorrhages in the skin and mucous membrane crews red purple discoloration of the skin.) |
| Leukemia: | Increase in cancerous white blood cells (leukocytes). |
| Acute myelogenous leukemia: | Immature granulocytes (myeloblasts) leukemia (AML) predominate. |
| Acute lymphatic leukemia (ALL): | Immature lymphocytes (lymphoblasts) predominate. This form is seen most often in children and adolescents onset is sudden. |
| Chronic myelogenous (myelocytic) leukemia (CML): | Both mature and immature granulocytes are present in large numbers in the marrow in the blood. |
| Chronic lymphocytic leukemia (CLL): | Abnormal numbers of relatively mature lymphocytes predominate in the marrow, Nick knows and spleen. |
| Mononucleosis: | Infectious disease marked by increased numbers of mononuclear leukocytes in a large cervical lymph nodes. (This disease is transmitted by the Epstein-Barr virus (EBV). |
| Multiple myeloma: | Malignant neoplasm of bone marrow. |
| Anemia: | Efficiency in erythrocyte or hemoglobin. |
| Aplastic anemia: | Failure of blood cell production in the bone marrow. |
| Hemolytic anemia: | Reduction in blood cells due to excessive destruction. |
| Pernicious anemia: | Lack of mature erythrocytes caused by an inability to explore vitamin B12 into the bloodstream. |
| Sickle cell anemia: | Hereditary disorder of abnormal hemoglobin producing sickle – shaped erythrocyte and hemolysis. |
| Thalassemia: | Inherited defects in ability to produce hemoglobin leading to hypochromia. |
| Hemochromatosis: | Excess iron deposits throughout the body. |
| Polycythemia vera: | General increase in red blood cells (erythremia). |
