  1. Composition of Blood     By Peter Krieg, Alex Robertson, and Dan Dymecki

  2. Plasma      Liquid Portion of Blood 55% of total blood  Contains important dissolved substances Cellular Material  Cells suspended in blood 45% total of blood Red blood cells White Blood Cells Platelets Composition of Blood

  3. Blood Plasma • 90% water • 1% Protein               • 1% Inorganic Ions •  Sodium • Potassium • Chloride • 1% Organic Substances •  Digested substances • glucose, sucrose and amino acids • Waste products • Carbon dioxide

  4. Red Blood Cells • Can change shape without breaking •  Contain hemoglobin • Essential for binding with oxygen and carbon dioxide, so blood can carry these gases •  Contains iron • Give blood red color •  Element gases mentioned attach to

  5. White Blood Cells • Many different types: neutrophils,eosinophils,basophils, monocytes • Most well known one: lymphocytes  • T cells • Activate natural killer cells • B cells • Produce antibodies • Natural killer cells • Once activated, release cytotoxic granules, destroying non-self altered cells

  6. Platelets •  Fragments of cells • Promote blood clotting mechanisms • Contain proteins on surface which allow attachment to each other and breaks in blood vessel wall • Contain granules which can produce other proteins to aid in clotting breaks in blood vessel
