  24. pericardial cavity
    fluid-filled cavity between the pericardial layers
  25. ventricle
    lower right and left chambers of the heart
  26. heart valves
    structures within the heart that open and close with the heartbeat to regulate the one-way flow of blood

  31. valves of the veins
    valves located at intervals within the liniing of veins, especially in the legs, which constrict with muscle action to move the blood returning to the heart
  32. arteries
    vessels that carry blood from the heart to the arterioles

  37. veins
    vessels that carry blood to the heart from the venules
  38. systemic circulation
    circulation of blood throughout the body via arteries, arterioles, capillaries, venules, and veins to deliver oxygen and nutrients to body tissues
  39. coronary circulation
    circulation of blood through the coronary blood vessels to deliver oxygen and nutrients to the heart muscle tissues
  40. pulmonary circulation
    circulation of blood from the pulmonary artery through the vessels in the lungs and back to the heart via the pulmonary vein, providing for the exchange of gases
