- Dietary requirements for RBC production
- Iron, Vitamin b12, Folic Acid, Proteins
- Why is Vitamin b12 needed for RBC prod.?
- needed for dna synthesis
- Why is Folic acid needed from RBC prod?
- Dna synthesis
- What is anemia?
- The blood has low 02 carrying cpacits
- What causes anemia?
- Low # of RBC's, decreased hemoglobin content, or abnormal hemoglobin.
- Hemmoraghic anemia is due to..
- Blood loss
- Hemolytic anemia is...
- RBC's dying early
- Hemolytic anemia is caused by
- infections, transfusion reactings, abnormal hemoglobin
- Aplastic anemia is..
- red marrow is destroyed or inhibited
- Aplastic anemia is caused by
- bacterial toxins, drugs, ionizing radiation
- Aplastic anemia can cause
- Clotting problems, imunity problems (no RBC)
- Iron deficient can be caused be
- Low iron levels, hemorrage.
- Who is most succeptible to iron deficient anemia?
- Females--monthly flow.
- Pernicious anemais is caused by a
- Deficiency of vitamin b12 (more specifically, intrinsic factor)
- Sickle cell anemia--
- inflexible RBC's due to low oxygen. Rupture easier, and jam blood vessels.
- Sickle cell anemia can be treated with
- Blood transfusions
- Polycythemia causes..
- too many rbc's to be made, high viscosity, sludge (flow slowly)
- Polycythemia can cause
- clots, storke, heart failure
- Polycythemia can be caused be
- bone marrow cancer or high altitidue, blood doping, injection of EPO
- Leukocytes riddle
- Never let monkeys eat bannas (most to least)
- Can WBC's slip out of capilaries?
- Yes.
- Out of blood, WBC's move by
- amoeboid motion
- WBC's slipping out of capilarries is called
- Diapedisis
- Granulocytes have granules in there..
- cytoplasm and multilobed nucleus
- Wright stains
- Show granulocytes and identify WBCs
- Neutrophils
- Most numerous WBC
- What do neutrophils do?
- Phagocytizes bacteria and forms pus in the process.
- Neutrophils take up..
- blue and red dyes (acidic and basic)
- Eisinophils are...
- acid loving
- Eisinophils kill..
- parasitic worms and antigen'
- Eisonophils take up which dye(s)
- Red (acid)
- Basophils are the...
- least numerous
- Basiphils are part of the
- inflammatory response
- Basophils release
- heparin (anti-coag) and histamine (dilates and attracts WBCs)
- Basopihls stain..
- blue-purple with basic dye
- Agranulocytes--
- No granules! (or not visible)
- Agrnulocytes include
- Lymmphocytes and monocytes.
- Lymphocytes attack
- Directly or releasing antibodies
- T lymphocytes
- Directly attack virus and tumor cells Mature in THYMUS
- B lymphocytes
- Make more plasma cells to produce anitbodies (produced in bone marrow)
- Moncyte is largest or smallest?
- LARGEST
- What do monocytes do?
- Phagocytizies large anitgens or dead cells
- Monocytes develop into a what in body tissues?
- Macrophage.
