Presentation Transcript

  1. Unit E: Hematology Competency Analyze the anatomy and physiology of the blood.

  2. Specific Objectives • 1H07.01 Explain the structure of the blood.

  3. Hematology Average adult has 8-10 pints of blood.

  4. Composition • PLASMA – liquid portion of blood without cellular components. • SERUM – plasma after a blood clot is formed. • Cellular elements are red cells, white cells and platelets.

  5. PLASMAStraw colored, contains… • Water • Blood proteins • Nutrients • Electrolytes • Hormones, vitamins, enzymes • Metabolic waste products • Plasma proteins

  6. ERYTHROCYTES • Shape = biconcave discs • Red Blood Cells www.rkm.com.au/.../CELL-Red-Blood-Cell-150.jpg

  7. HEMOGLOBIN • Gives red color, heme is iron and globin is protein. • Function = transports oxygen to tissues and carbon dioxide away from cells • Normal – men =14-18 gm women = 12-16 gm

  8. LEUKOCYTES • White Blood Cells • Larger than erythrocytes • 5 types • Normal leukocyte count = 3,200 – 9,800 • Types of White Cells 1. Neutrophils 4. Lymphocytes 2. Eosinophils 5. Monocytes 3. Basophils http://www.regenkit.com/images/leukocytes.jpg

  9. Basophils Basophils produce… HEPARIN – an anticoagulant (that means it stops blood from clotting)

  10. THROMBOCYTES (Platelets) • Smallest of solid components of blood • Synthesized in red marrow • Not cells – fragments of megakaryocytes • Necessary for the initiation of the blood clotting process

  11. Thanks for being so attentive. • Did you know that each blood donation has the potential to save three lives?
