P. 641 HI 17.1 of RBC production
- Injecting EPO results in hematocrit level going from 45% ( healthy) to 65%
- Dehydration in athletes can cause clots, stroke, heart failure
P. 642 - 644 Erythrocyte (RBC) disorders
- Anemia
- Blood O2 level to low to help w/ normal metabolism
- Anemia types
- Hemorrhagic anemia
- Caused by blood loss
- Not enough blood cells produced
- Iron-deficiency anemia
- Result of hemorrhagic anemia and not enough iron intake
- Erythrocytes produced and microcytes
- Microcytes - small and pale
- Pernicious anemia
- Autoimmune disease, elderly people
- Stomach cells destroyed
- Cells produce intrinsic factor
- Intrinsic factor- needs to be present for vitamin b12 to work
- Renal anemia
- Caused by little epo
- Aplastic anemia
- Caused by red marrow destroyed by drugs/chemicals
- Can lead to blood clot
- Too many blood cells destroyed
- In hemolytic anemias
- Thalassemias
- Mediterranean people
- One globin chain not their/not working well
- Thin erythrocytes
- Sickle cell anemia
- Caused by abnormal hemoglobin
- Red blood cells become crescent shaped when O2 level is low
- Polycythemia
- Too much erythrocytes - raises blood viscosity
- Polycythemia vera
- Bone marrow disease
- Dizziness and high RBC count (8 to 11 million cells)
- Secondary polycythemias
- Little O2 available
- EPO produced increases
- Blood doping
- Artificial polycythemia
- Some blood cells taken out of body and stored, fe days later (athletic event)
athlete injects blood cells for higher performance
P. 649 -Clinical use of EPOs and CSFs
- EPOs and CSFs energize bone marrow of cancer patients who are getting chemo
- Increase protection in AIDS patients
P. 649 - Leukocyte (WBC) Disorders
- Leukopenia
- abnormal low white blood cell count
- Leukemia
- Too much white blood cells produced
- Acute leukemia - children
- Chronic leukemia- adults
- Infectious mononucleosis
- Common in young adults
- Aka kissing disease
- Too much lymphocytes
- Symptoms- achy, tired, sore throat
P. 655 - 656 - Homeostatic disorders
- Thromboembolic disorders
- Cause clot formation
Document Summary
Ch 17: 641 hi 17. 1 of rbc production. Injecting epo results in hematocrit level going from 45% ( healthy) to 65% Dehydration in athletes can cause clots, stroke, heart failure: 642 - 644 erythrocyte (rbc) disorders. Blood o2 level to low to help w/ normal metabolism. Result of hemorrhagic anemia and not enough iron intake. Intrinsic factor- needs to be present for vitamin b12 to work. Caused by red marrow destroyed by drugs/chemicals. One globin chain not their/not working well. Red blood cells become crescent shaped when o2 level is low. Dizziness and high rbc count (8 to 11 million cells) Some blood cells taken out of body and stored, fe days later (athletic event) athlete injects blood cells for higher performance: 649 -clinical use of epos and csfs. Epos and csfs energize bone marrow of cancer patients who are getting chemo. Increase protection in aids patients: 649 - leukocyte (wbc) disorders.
