2. Blood What is it? Thick, red liquid when taken out of the body
Blood that is centrifuged (spun fast) will separate into 2 main parts:

3. Blood - Plasma
Mainly H2O
Dissolved in the water:

4. Blood - Plasma Plasma proteins: Albumins: Globulins: Immunoglobulins:
Fibrinogen:

5. Blood – Cellular component
Three main types:
Red blood cells: erythrocyte
White blood cells: leukocytes
Platelets: small cell fragments

6. Blood cells: Erythrocytes
Also called RBCs
Small, biconcave cells
Anucleate
Made in the bone marrow
Last about 120 days before being destroyed by the liver and spleen

7. Bone marrow

8. Blood cells: Erythrocytes
Main role is to carry oxygen
Why are the cells red?
Why are they anucleate?

9. Blood cells: Erythrocytes
Main role is to carry oxygen

10. Blood cells: Leukocytes
Also called WBCs
Much larger cells that contain a nucleus
Two major types:
Granular
Agranular

11. Blood cells: Leukocytes
Granular leukocytes:
Contain granules in their cytoplasm (looks like grains of sand)
Granules are:
Three types:
Neutrophils
Eosinophils
Basophils

12. Blood cells: Leukocytes
Agranular leukocytes
Two types:
Lymphocytes
Monocytes (macrophages)
What is their role?

13. Blood cells: Leukocytes
Agranular leukocytes
Phagocytosis:
Once one of these finds a foreign cell, describe the sequence of events that occur.

14. Blood cells: Platelets
Specialized cell fragments
Produced where?
Responsible for?

15. Blood cells: Platelets
Blood clotting: Coagulation
Describe how a blood clot forms.

16. Blood cells: Platelets
Blood clotting: Coagulation
What is a stroke?

17. What you need to know!
Figure 6 on page 484 and the section “Counting Blood Cells”
Don’t need to know exact numbers but relative amounts
Also, since we already covered this, the Blood Type section on pages , are considered fair game for the Quest
