  1. atrium
    upper right or left chamber of the heart
  2. endocardium
    membrane lining the cavities of the heart
  3. epicardium
    membrane forming the outer layer of the heart
  4. interatrial septum
    partition between the right and left atria
  5. interventicular septum
    partition between the right and left ventricles
  6. myocardium
    heart muscle
  7. pericardium
    protective sac enclosing the heart composed of two layers with fluid between
  8. visceral pericardium
    layer closest to the heart (visceral = pertaining to organ)
  9. parietal pericardium
    outer layer (parietal = pertaining to wall)
  10. pericardial cavity
    fluid-filled cavity between the pericardial layers
  11. ventricle
    lower right or left chamber of the heart
  12. heart valves
    structures within the heart that open and close with the heartbeat to regulate the one-way flow of blood
  13. aortic valve
    heart valve between the left ventricle and the aorta
  14. mitral valve
    bicuspid valve
    heart valve between the left atrium and left ventricle (cuspis = point)
  15. pulmonary semilunar valve
    heart valve opening from the right ventricle to the pulmonary artery (luna = moon)
  16. tricuspid valve
    valve between the right atrium and the right ventricle
  17. valves of the veins
    valves located at intervals within the lining of veins, especially in the legs, which constrict with muscle action to move the blood returning to the heart
  18. arteries
    vessels that carry blood from the heart to the arterioles
  19. aorta
    large artery that is the main trunk of the arterial system branching form the left ventricle
  20. arterioles
    small vessels that receive blood from the arteries
  21. capillaries
    tiny vessels that join arterioles and venues
  22. venules
    small vessels that gather blood from the capillaries into the veins
  23. veins
    vessels that carry blood to the heart from the venues
  24. systemic circulation
    circulation of blood throughout the body via arteries, arterioles, capillaries, venules, and veins, to deliver oxygen and nutrients to body tissues
  25. coronary circulation
    circulation of blood through the coronary blood vessels to deliver oxygen and nutrients to the heart muscle tissue
  26. pulmonary circulation
    circulation of blood form the pulmonary artery through the vessels in the lungs and back to the heart via the pulmonary vein, providing for the exchange of gases
