  • 11. Considered a connective tissue because itcontains cells, a liquidground substance (called plasma), and dissolvedprotein fibers. About four times more viscous (or thicker) thanwater. Can be broken down into its liquid and cellularcomponents by amachine called a centrifuge. blood is withdrawn from a vein and collected ina centrifuge tube tube is placed into the centrifuge, which thenspins it in a circularmotion for several minutes rotational movement separates the blood intoliquid and cellularcomponents Copyright © 2004 Pearson Education, Inc., publishing as Benjamin Cummings

  • 13. Blood Components: Cells• Erythrocytes • Red Blood Cells (RBC) • O2 CO2 transport• White Blood Cells (WBC) • Immune defense • Phagocytosis• Platelets: clottingCopyright © 2004 Pearson Education, Inc., publishing as Benjamin Cummings
  • 14. Summary • Blood is about 50% plasma, water solvent solutes: ions, elements, gasses, proteins, wastes nutrients • White blood cells function in internal defense • Iron in hemoglobin is key to RBC transport of O2 • Platelet activation initiates clot formation • Clotting prevents blood loss but is a problem in cardiovascular diseaseCopyright © 2004 Pearson Education, Inc., publishing as Benjamin Cummings
