1. Composition of Blood
1. Red Blood Cells (Erythrocytes)

· Hemoglobin – Oxyhemoglobin / Deoxyhemoglobin

· Red blood cell count = # of red blood cells in a cubic millimeter

· Lifespan of reb blood cells = 120 days

2. White Blood Cells (Leukocytes)
1. Types of White Blood Cells

· Lifespan – days, months, years

1. Granular Leukocytes (Neutrophils, Eosinophils, Basophils)
2. Agranular Leukocytes (Monocytes and Lymphocytes)

3. Platelets (Thrombocytes)

· Thrombocytopenia

· Lifespan = 10 days

4. Hematopoiesis

· Red bone marrow

· All cells begin with the multipotent stem cell

5. Plasma

· Liquid

· 92% water

· Molecules, including plasma proteins – gamma globulin, fibrinogen

2. Functions of Blood
1. Transport

· Exchanges between Blood and Tissue Fluid

2. Blood Clotting

· Platelet plug

· Prothrombin

· Thrombin

· Fibrin

3. Blood Groups and Typing
1. ABO System

· Agglutination

· O = universal donor

· AB = universal recipient

B. Rh System

· Rh+ = antigen

· Rh- = no antigen

C. Blood Typing

D. Diseases of the Blood

· Hemophilia

· Anemia

· Leukemia

· Sickle Cell Anemia
