| lymphocytes |
cells with large nuclei |
| lymphocytes |
produce antibodies & chemicals that control disease, allergic reactions, tumors |
| platelets |
cell fragments, thrombocytes |
| platelets |
smallest formed elements in blood |
| platelets |
not cells, particles pinched off bits of cytoplasm formed from large cells called megakaryocytes |
| platelets |
plays major role in prevention of blood loss via clot formation |
| hemostasis |
blood loss |
| hemopoiesis (hematopoiesis) |
process of blood cell formation |
| blood clot formation |
(blank) |
| blood cells |
formed from pluripotent stem cells |
| pluripotent stem cells |
found within bone marrow and lymphatic tissue |
| myeloid stem cells |
develope within "red" bone marrow |
| myeloid stem cells |
give rise to platelets, RBCs, WBCs (not lymphocytes & monocytes) |
| lymphoid stem cells |
found within lymph nodes, thymus, spleen bone marrow |
| lymphoid stem cells |
form lymphocytes & monocytes |
| anemia |
RBC disorder, "decrease" in number of RBC, hemoglobin content, amt of iron in blood |
| hematocrit |
measuring the percent volume that the blood cell sediment occupies |
| *anemia symptoms |
skin & mucosal pallor, dyspnea, heart palpitations, soft systolic murmurs, lethargy, fatiguability |
| hemolytic anemias |
inherited disorders, formation of abnormal hemoglobin molecule that results in deformation & increased fragility of RBCs |
| spherocytosis |
instead of biconcave, RBC are rounded, rupture easily, causes "chronic" anemia |
| sickle cell anemia |
ingerited disease of hemoglobin formation, sickle-shaped RBCs, readily broken down, chronic anemia |
| hemolyzed |
broken down |
| thalassemia |
inherited disorder, abnormally shaped hemoglobin, found in mediterranean populations |
| iron deficiency anemia |
low hemoglobin level due to iron deficiency |
| pernicious anemia |
low RBC due to lack of vitamin B12 |
| aplastic anemia |
low RBC caused by bone marrow destruction caused by chemotherapy, radiation, antibiotics, toxic chemicals |
| folate-deficiency anemia |
low RBCs due to lack of folic acid (Vit B9) common among alcoholics & malnourished individuals |
| acute blood loss anemia |
occurs after hemorrhages with trauma or surgery or any sudden blood loss |
| chronic blood loss anemia |
results from frequent or long-term blood loss associated with cancer or slow bleeding ulcers |
