3. Components of Blood

4. What are the parts of blood?
Plasma-
Clear, yellow colored liquid
Makes up 55%
Contains water (~90%) and solutes (~10%)
-Amino acids, proteins, carbs, sugars, ions, electrolytes, and wastes, hormones

5. Plasma (cont.) ~45% remainder is Hematocrit /Blood cells
-American Red Cross Donations
-Restrictions?
-Hematopoesis
Hem=?
Poesis=?
Total blood volume
-adult males= 5-6 Liters
-adult females= 4-5 Liters
Why the discrepancy?

6. 2. Erythrocytes-
AKA-red blood cells
Biconcave cells-larger surface area
Contain hemoglobin
Lack a nucleus
Mid-sized
Most numerous cell in the blood
Fxn-transport Oxygen and Carbon Dioxide

7. 3. Leukocytes
(see pg. 658 in Marieb)
AKA-white blood cells
All Larger than RBCs
Least numerous cells in the blood
Contains nucleus
Fxn: fight disease

8. 3. Leukocytes
Broken into two groups-
Granulocytes- cells which have a grainy cytoplasm
Agranulocytes- cell which do not have a grainy cytoplasm

9. There are 5 Types of WBCs: Granulocytes- 1-Neutrophils-use phagocytosis (contain many lysosomes) on Bacteria 2-Eosinophils-use phagocytosis to engulf parasitic worms, control inflammation and allergic rxns, bilobed nucleus 3--Basophils-help with blood clotting (heparin), histamine-allergic reactions

10. There are 5 Types of WBCs: Agranulocytes- 4-Monocytes-use phagocytosis to engulf large invading organisms (macrophages) 5-Lymphocytes-major immunity cell, produce antibodies T-lymphocytes- attack infected cells B-lymphocytes- produce antibodies

11. Portions of very large cells ½ size of RBC WBC <# < RBC
4. Thrombocytes-
AKA-platelets
Portions of very large cells
½ size of RBC
WBC <# < RBC
FXN-stop blood flow forming a platelet plug
Summary clip

12. 4. Thrombocytes-
Hemostasis- stopping of blood flow at a damaged tissue
Coagulation- formation of a blood clot, platelets release chemicals which will assist in the coagulation, also assisted by protein fibrinogen]
