    • Deoxygenated blood 

      Blood containing a low concentration of O2
    • Oxygenated blood 

      Blood contains high level of oxygen
    • Vena cava
      Carried deoxygenated blood from the body into the right atrium
    • Right atrium / right ventricle
      Tricuspid valve- opens and closes to prevent backflow
    • Pulmonary vein
      Receives deoxygenated blood from the right ventricle to take the lungs to prescience oxygen
    • lungs
      where gaseous exchange occurs to turn deoxygenated blood onto oxygenated blood
    • Pulmonary vein
      Brings oxygenated blood from the lungs to the left atrium
    • Left atrium / left ventricle
      Bicuspid valve - opens and closes to prevent backflow
    • Aorta
      Main arterty. carries oxygenated blood from the left ventricle to take oxygen to the working muscles
    • Blood vessels
      Three main blood vessels
      1. capillaries
      2. veins
      3. arteries
    • Arteries
      • Thick electic wall
      • small internal diameter (lumen)
      • carries blood at high press
    • Veins
      • Thinner putter wall
      • large internal diameter ( lumen)
      • contain valves to prevent backflow
    • Capillaries
      • extemely thing walls allow gaseous exchange
    • Vasoconstriction
      Inner diameter will narrow to reduce blood flow to inactive areas
    • Vasodilation
      Inner diameter widens to increase blood flow to the active areas
