1. Blood disorders and Hematstasis

2. Anemia  what is it?

3. Anemia Decrease in oxygen carrying ability

4. 3 Causes: 1. 2. 3.

5. Examples of causes 1. Low RBC: bleeding, RBC’s are destroyed (bacterial infection) 2. Low hemoglobin: low iron in diet; slow, prolonged bleeding 3. Abnormal hemoglobin: sickle cell anemia

6. Symptoms: 1. 2. 3. 4.

7. Symptoms: 1. Fatigue 2. Tachycardia 3. Feeling cold 4. Dizziness or fainting

8. Sickle cell anemia

9. Sickle Cell: Who carries the trait?

10. Sickle Cell: Who carries the trait? (don’t write) Prevalent in African Americans: 1 in 12 carries the trait 70,000-80,000 Americans have sickle cell anemia

11. Why this group?

12. Malaria Range in World

13. Malarial range in Africa

14. How does trait work? genetics

15. How does trait work: genetics (write) If have 2 genes for SCA: have disease If have 1 gene for SCA: ½ of RBC’s are sickle shaped,you won’t get malaria

16. Symptoms of SCA Pain Anemia

17. Hemophilia “free bleeder” Blood can’t clot Bruise easy Life threatening

18. Leukemia Too many White blood cells made They don’t work well Crowd out normal cells
