1. An Introduction
HEMATOLOGY

1a. Without references identify basic facts and terms about hematology with a minimum of 70% accuracy.
(1) Hematology (2) Circulatory System (3) Origins of Blood Cells (4) Hematological Diseases (5) Specimens for Hematology

3. HEMATOLOGY Anemia Leukemia Hemophilia
Branch of medicine that studies blood cells and blood-forming tissue
Includes hemostasis (the process of stopping bleeding)
Tests can detect diseases such as
Anemia
Leukemia
Hemophilia

4. Circulatory System
Circulation
Blood circulates from the heart to the lungs to pick up O2
Oxygenated blood returns to the heart to be pumped out to the tissues
O2 is exchanged for CO2 in the tissues
Blood returns to the heart and lungs to release the CO2 by exhaling

6. Types of Vessels
Arteries- Carry blood with O2 (excluding pulmonary artery)
Veins- Carry blood with CO2 (except for pulmonary vein)
Capillaries- Smallest blood vessel (point of gas exchange

7. Composition of Blood
Volume - approximately 5 liters in an adult
Components (mostly water)
Plasma – 50-60% of blood volume; mostly H2O with proteins, carbohydrates, lipids, hormones and antibodies
X 5

8. Cellular Elements major function - transport O2 and CO2
Erythrocytes (RBCs)
major function - transport O2 and CO2
life span days
Leukocytes (WBCs)
major function - provide immunity and defense against infection, (5 types)

9. Cellular Elements major function – hemostasis life span - 10 days
Thrombocytes (platelets)
major function – hemostasis
life span - 10 days

10. Origins of Blood Cells
Hemopoiesis - formation and development of blood cells
Liver (fetus)
Bone marrow (adults) – blood cells mature in marrow and are released into circulation

11. Hematological Diseases
Leukemia – overproduction of WBCs
Anemia – decreased number of RBCs
Thrombocytopenia – decreased number of platelets
Polycythemia – increased number of all types of blood cells
Inherited diseases – hemophilia and sickle cell

12. Specimens for Hematology
Capillary and venous blood used
Complete Blood Count
Specimen of choice – whole blood with EDTA anticoagulant
Coagulation testing
Specimen of choice – whole blood with sodium citrate anticoagulant
