Blood Lab
Maybe stuff on Blood lab exam
| Term | Definition |
|---|---|
| Erythrocyte | An anucleate blood cell filled with hemoglobin that transports oxygen through the body |
| Leukocyte | A type of blood cell that plays various roles in the immune system |
| Granulocyte | A type of leukocyte that contains cytoplasmic granules that are visible with staining |
| Neutrophil | A type of granulocyte with lilac-colored granules and multi-lobed nuclei; these cells are heavily involved in the phagocytosis of bacteria |
| Eosinophil | A type of granulocyte with bilobed nuclei and red-stained granules; these cells are involved in allergy responses and fighting parasitic infections |
| Basophil | A type of granulocyte with bilobed nuclei and dark purple-stained granules; these cells are involved in mediating inflammation |
| Agranulocyte | A type of leukocyte that lacks visible cytoplasmic granules |
| T lymphocyte | A type of agranulocyte that facilitates other functions of the immune response, kills cancer cells, and kills infected host cells. |
| B lymphocyte | A type of agranulocyte that secretes antibodies when activated |
| Monocyte | A type of agranulocyte with horseshoe-shaped nuclei that mature into macrophages, which are very active phagocytes. |
| Platelets | Small cellular fragments involved in blood clotting |
| Antigen | Unique glycoprotein on the surface of all cells and present on most biological molecules |
| Antiserum | A solution containing antibodies that bind with specific antigens |
| Antibody | Protein secreted by B lymphocytes; each antibody type binds to a specific antigen |
| Universal donor | Type O– blood, which does not have A, B, or Rh antigens on the surface of its cells, so it can be accepted by a person of almost any blood type without triggering an immune response |
| Universal recipient | A person with AB+ blood who has erythrocytes with A, B, and Rh antigens and so lacks anti-A, anti-B, and anti-Rh antibodies and can therefore accept all blood types without triggering an immune response |
| Erythrocyte Nucleus Shape,Cytoplasm and/or Granule Color,Function(s),Prevalence | Anucleate; Red; Carry oxygen; 42–47% the volume of whole blood |
| Neutrophil Nucleus Shape,Cytoplasm and/or Granule Color,Function(s),Prevalence | 3–5 lobes; Lilac cytoplasm, granules inconspicuous; Phagocytes active against bacteria; 50–70% of leukocytes |
| Eosinophil Nucleus Shape,Cytoplasm and/or Granule Color,Function(s),Prevalence | Bilobed; Red; Defense against parasites and involved in allergy; 2–4% of leukocytes |
| Basophil Nucleus Shape,Cytoplasm and/or Granule Color,Function(s),Prevalence | Lobed, often obscured by granules; Dark purple; Enhance inflammation; 0.5–1% of leukocytes |
| Lymphocyte Nucleus Shape,Cytoplasm and/or Granule Color,Function(s),Prevalence | Spherical; Light blue; Attack foreign cells, make antibodies; 25–45% of leukocytes |
| Monocyte Nucleus Shape,Cytoplasm and/or Granule Color,Function(s),Prevalence | U-shaped; Light blue; Active phagocytes; 3–8% of leukocytes |
| Platelet Nucleus Shape,Cytoplasm and/or Granule Color,Function(s),Prevalence | Anucleate; Blue/purple, tiny fragments of cells; Clotting; < 1% of whole blood |
| A+ Antigens present; antibodies present | A, Rh ; Anti-B |
| A- Antigens present; antibodies present | A; Anti-B, Anti-Rh |
| B+ Antigens present; antibodies present | B, Rh; anti-A |
| B- Antigens present; antibodies present | B; Anti-A, Anti-Rh |
| AB+ Antigens present; antibodies present | A, B, Rh; None |
| AB- Antigens present; antibodies present | A,B; Anti-Rh |
| O+ Antigens present; antibodies present | Rh; Anti-A, Anti-B |
| O- Antigens present; antibodies present | None; Anti-A, Anti-B, Anti-Rh |
| T/F? The liquid portion of blood is known as plasma. | True |
| T/F?Erythrocytes are generally involved in some aspect of the immune system. | False: Leukocytes are involves |
| T/F? The granulocytes include the neutrophils, eosinophils, and basophils. | True |
| T/F? Eosinophils are involved in mediating responses to parasitic worms and allergies. | True |
| T/F? Lymphocytes leave the blood and become macrophages, very active phagocytes. | False: Monocytes become macrophages |
| Erythrocytes carry oxygen on the protein.. | hemoglobin |
| Antibodies are produced by ___ and bind to specific ____ on erythrocytes, causing ____ , or clumping of erythrocytes. | B lymphocytes; antigens; agglutination |
