2. Blood
Artery
White blood cells
Platelets
Red blood cells

3. Composition of blood
Blood transports materials through out the body inside blood vessels.

4. Function Blood Deliver O2 Remove metabolic wastes
Maintain temperature, pH, and fluid volume
Protection from blood loss- platelets
Prevent infection- antibodies and WBC
Transport hormones

5. Blood
Plasma-55%
Buffy coat-<1%
Formed elements-45%

6. Blood Plasma Components-55%
90% Water
8% Solutes:
Proteins
Albumin (60 %)
Alpha and Beta Globulins
Gamma Globulins
fibrinogens
Gas
Electrolytes

7. Buffy Coat- <1%
Platelets
Leukocytes

8. Formed Elements of the Blood-45%
Erythrocytes (red blood cells)
Leukocytes (white blood cells)
Platelets (thrombocytes)

9. Blood Cell Production

10. RBC Diseases
Anemia- when blood has low O2 carrying capacity; insufficient RBC or iron deficiency.
Factors that can cause anemia- exercise, B12 deficiency

11. Types of Leukocytes Granulocytes Neutrophils- 40-70% Eosinophils- 1-4%
4,000-11,000 cells/mm 3
Never let monkeys eat bananas

13. Blood Types
Type A
Type B
Type AB
Type O

14. Blood Typing
Blood type is based on the presence of 2 major antigens in RBC membranes-- A and B
Blood type Antigen Antibody
A A anti-B
B B anti-A
A & B AB no anti body
Neither A or B O anti-A and anti-B
Antigen- protein on the surface of a RBC membrane
Antibody- proteins made by lymphocytes in plasma which are made in response to the presence of antigens.
They attack foreign antigens, which result in clumping (agglutination)

15. Type A b b b b b b b

16. Type B a a a a a a a

17. Type O a b a a a b b a a b

18. Type AB

21. Leukemia
Form of cancer in which the bone marrow makes too many white blood cells.
