  1. (Interventricular)Septum: The structure that divides the 2 ventricles of the heart
  2. 5th and 6th: The apex of the heart usually sits at the same approximate level as the space between these 2 ribs
  3. Aorta: the largest artery of the human body
  4. Atria: The chambers of the heart whose function is to receive blood from the veins
  5. Auricles: The "ear-like" structures that extend from the atria
  6. AV (Atrioventricular): The valves that are located between the atria and the ventricles
  7. Base: The part of the heart that rests just below the right second rib
  8. Brachiocephalic: The branch of the aorta that divides into the right subclavian and right common carotid arteries
  9. Cardiac Muscle: The type of tissue that compromises the bulk of the myocardium
  10. Cardiovascular: The heart is an organ of this body system
  11. Carry blood away from the heart: The function of an artery
  12. Cervical Fascia: The pericardium attaches to this structure inferiorly
  13. Cordae Tendinea: The scientific term for the "heart strings" that extend from the AV cusps to the papillary muscles
  14. Endocardium: The lining of the heart
  15. Endocardium: The tunica interna is continuous with this layer of the heart

  23. Pericardium: The sac surrounding the heart
  24. Right Atrium: The superior vena cava attaches to this heart chamber
  25. Sternum: The bone that protects the heart anteriorly
  26. To carry blood to the heart: The function of a vein
  27. To pump blood to the organs and the body: The function of the heart
  28. Tunica Externa, Tunica Media, and Tunica Interna: The three layers of an atery from outermost to innermost
