1. Blood Constituents

2. Characteristics Human - about 5-6 L man, 4-5 L woman
Consists of – plasma (fluid), about 55%
- formed (solid) elements about 45%
1) Red blood cells
2) White blood cells
3) Platelets

3. Results of Centrifugation (formed elements collect at bottom)
(55%)
Formed Elements
(45%)

4. FUNCTIONS of PLASMA Yellowish tint, liquid component of blood
- 90 % water
dissolved substances nutrients
(nutrients, antibodies, hormones, waste)
transports: nutrients, antibodies, hormones, proteins, cellular waste to excretory organs

5. Red Blood Cells

6. Functions of RBC`s Transports carbon dioxide
Hemoglobin (in Red Blood Cells) transport of oxygen

7. WBC`s (White Blood Cells)
defense against disease.
-neutralize antigens
(bacteria, viruses, harmful foreign elements)
- rid body of debris, dead or damaged cells

8. Platelets

10. Functions of Platelets
Irregular fragments of cells(not really cells)
Help in blood-clotting

11. Anemia Disease- lack of oxygen 3 causes: 1. not enough RBC’s
2. not enough hemoglobin in RBC’s
3. Abnormally formed hemoglobin
