  1. WHAT DOES THE CIRCULATORY SYSTEM TRANSPORT TO THE BODY'S CELLS?
    OXYGEN AND NUTRIENTS
  2. WHAT IS THE TRANSPORTATION VEHICLE FOR OXYGEN AND NUTRIENTS?
    THE BLOOD
  3. THE FOUR MAIN PARTS OF THE CIRCULATORY SYSTEM ARE:
    • 1. THE PUMP - HEART

    • 3.THE CIRCULATING FLUID - THE BLOOD
    • 4. AN AUXILLIARY SYSTEM - THE LYMPHATIC SYSTEM
  4. SYSTOLE

  36. WHAT DO VEINS CARRY?
    DEOXYGENATED BLOOD BACK TO THE HEART TO BE SENT TO THE LUNGS FOR EXHALING OF CARBON DIOXIDE AND TO PICK UP A NEW SUPPLY OF OXYGEN.
  37. LYMPHATIC SYSTEM

  64. CORONARY ARTERY DISEASE
    DISEASE OF TEH ARTERIES TAHT SURROUND THE HEART, CARRYING OXYGEN AND NUTRIENTS TO THE MYCARDIUM
  65. EMBOLISM
    FOREIGN MATTER THAT ENTERS AND CIRCULATES IN THE BLOODSTREAM
  66. LEUKEMIANE
    MALIGNANT DISEASE OF THE BONE MARROW OR LYMPHATIC TISSUE
  67. MURMUR

  68. PHLEBITIS
    INFLAMMATION OF A VEIN
  69. SICKLE CELL ANEMIA
    HEMOGLOBIN DEFECT IN THEIR MOLECULAR STRUCTURE THAT CAUSES THE CELLS TO BECOME SICKLE SHAPED, OF WHICH CAN NOT PASS EASILY THROUGH BLOOD VESSELS.

  71. VARICOSITIES (VARICOSE VEINS)
