  6. RED BLOOD CELLS • Hemoglobin • Red pigment in erythrocytes • Erythropoiesis • Manufacture of red blood cells • Occurs in red bone marrow • Hemolysis • Rupture of red blood cell © 2004 Delmar Learning, a Division of Thomson Learning, Inc.

  7. WHITE BLOOD CELLS • Types of Leukocytes: • Granulocytes • Neutrophils • Eosinophils • Basophils • Agranulocytes • Lymphocytes • Monocytes © 2004 Delmar Learning, a Division of Thomson Learning, Inc.

  8. INFLAMMATION • Occurs when tissues are subjected to chemical or physical trauma • Symptoms: • Redness • Local heat • Swelling • Pain © 2004 Delmar Learning, a Division of Thomson Learning, Inc.

  9. THROMBOCYTES(BLOOD PLATELETS) • Thrombocytes are the smallest of the solid components of blood • Coagulation is clotting of the blood • The time it takes for blood to clot is known as clotting time • Human clotting time: 5 to 15 minutes © 2004 Delmar Learning, a Division of Thomson Learning, Inc.

  10. BLOOD TYPES • Four major groups of blood • A - AB • B - O • Blood type inherited from parents • Antigen - protein present in blood • Antibody - protein in plasma © 2004 Delmar Learning, a Division of Thomson Learning, Inc.

  11. RH FACTOR • The Rh factor is found on the surface of red blood cells • Rh positive • Rh negative © 2004 Delmar Learning, a Division of Thomson Learning, Inc.
