  1. forms the upper right border of the heart and drains venous blood from the systemic and coronary circulation
    right atrium
  2. a small, conical muscular pouch that is continuous with the atrium
    right auricle
  3. forms the thin medial wall of the right atrium and seperates the right and left atria from each other
    interatrial septum
  4. a pre-birth opening in the interaial septum, eventually becomes the fossa ovalis
    foramen ovale
  5. appears in the superior part of the fossa ovalis in 10% of neonates with congenital heart defects
    atrial septal defect (ASD)
  6. returns venous blood from the head and neck region
    superior vena cava
  7. returns venous blood from the coronary circulation
    coronary sinus
  8. valve that seperates R atrium from R ventricle
    tricuspid valve
  9. a thrombus that obstructs a vessel
    embolus
  10. when there is a blockage of blood to the myocardium
    myocardial infraction
  11. forms most of the base and posterior aspect of the hear
    L atrium
  12. a thick and strong partition between the L and R ventricles
    interventricular septum
  13. a condition where the membrance area of the interventricular septum does not close all the way, % of all forms of congenital heart disease
    ventricular septal defect (VSD)
  14. allows blood flow from the left atrium to the left ventricle, has two leaflets
    biscuspid or mitral AV valve
  15. chordae tendineae
    connects the valve leaflets to conical papillary muscles on the floor of the ventricles
  16. pulmonary semilunar valve
    controls the opening from the R ventricle into the pulmonary trunk
  17. aortic semilunar valve
    controls the opening from the L ventricle into the aorta
  18. atherosclerosis
    lipid accumulation of the internal walls of the coronary arteries
  19. myocardial ischemia
    usually a tempoaray flow of blood to the myocardium
