Sanrio M. Canillo BBTE 2-1 BLOOD
Non-living fluid matrix plasma and formed elements Dull-red in color, depending on the amount of the oxygen carried Normal adult blood volume: 5 to 6 liters
Classification of Blood Cells Erythrocytes – Red Blood Cells Leukocytes – White Blood Cells
ERYTHROCYTES • 45 %of total blood volume • Small biconcave disk shaped cell • Contains HEMOGLOBIN • 1 red blood cell = 250 Million hemoglobin molecule • 1 hemoglobin molecule = 4 molecules of Oxygen • Normal blood contains men: 14 to 18 g, women: 12 to 16 g
LEUKOCYTES • Body’s defense against diseases • 4000 to 11000 WBC / cubic mm • 1% of the total blood volume • Forms a protective army that helps defend the body against damage by bacteria, viruses, parasites and tumor cells • Capable to slip in and out of the blood vessel by the process of DIAPEDESIS
PASSIVE CHEMOTAXIS - WBC alarm system; process where leukocytes can locate areas of tissue damage and infection in the body by responding to certain chemicals that diffuse from the damaged cells. • Leukocytosis - A condition wherein the total WBC count is over 11,000 / cubic mm. This generally indicates that a bacteria or viral infection is stewing in the body.
Leukopenia - a condition where there is an abnormally low WBC count, caused by the presence of certain drugs • Leukemia - a condition where there is excessive production of abnormal WBC. Bone marrow becomes cancerous and a huge number of WBC are produced rapidly.
THREE MAJOR GROUPS • GRANULOCYTES– 65% of total WBC count; WBC with granules. 3 types: • POLYMORPHONUCLEAR Leukocytes/ NEUTROPHILS • EOSINOPHILS • BASOPHILS
POLYMORPHONUCLEAR / NEUTROPHILS - Has the affinity to neutral dyes, appears color Violet
EOSINOPHILS - Colored red, has the affinity to acidic dyes
BASOPHILS - Has the affinity to basic dyes
AGRANULOCYTES– 35% of total WBC count; do not contain cytoplasmic granules. 2 types: • Lymphocytes • Monocytes
Agranulocytes Granulocytes
PLATELETS / THROMBOCYTES - important for blood clotting - 150,000 to 250,000/cubic mm; - very small that they may clamp together.
