  1. infarction
    tissue death caused by an obstruction of the tissue's blood supply
  2. ischemia
    restriction in blood supplies of tissues
  3. diastole
    is the period of time when the heart refills with blood after systole
  4. mitral stenosis
    narrowing of the mitral valve, which separates the upper and lower chambers on the left side of the heart
  5. arteriosclerosis
    hardening of the arteries
  6. arterial anastomosis
    the joining of two arteries
  7. myocardium
    the middle and thickest layer of the heart wall, composed of cardiac muscle.
  8. atheroma
    A fatty deposit in the inner lining (intima) of an artery, resulting from atherosclerosis.
  9. digitalis
    Digitalis is used to treat congestive heart failure (CHF) and heart rhythm problems (atrial arrhythmias). Digitalis can increase blood flow throughout your body and reduce swelling in your hands and ankles.
  10. patent ductus arteriosus
    • Patent ductus arteriosus (PDA) is a condition in which the ductus arteriosus does not close.
    • The ductus arteriosus is a blood vessel that allows blood to go around the baby's lungs before birth. Soon after the infant is born and the lungs fill with air, the ductus arteriosus is no longer needed. It usually closes in a couple of days after birth.
  11. nitroglycerin
    Nitroglycerin spray and tablets are used to treat episodes of angina (chest pain) in people who have coronary artery disease
  12. angina pectoris
    chest pain due to ischemia
  13. mitral valve prolapse
    a heart problem in which the valve that separates the upper and lower chambers of the left side of the heart does not close properly
  14. septal defects
    • also known as a "hole in the heart"
    • congenital defect
    • can be between the atria or ventricles
  15. systole
    The time period when the heart is contracting
  16. aneurysm
    an abnormal widening or ballooning of a portion of an artery due to weakness in the wall of the blood vessel

  19. what is the septa?
    divides the heart into right and left halves
  20. the opening between the right atrium and the right ventricle is controlled by which valve?

    • vascular damage
    • cardiac perforation
    • infection
    • hemorrhage or hematoma
    • in rare cases, death
  28. what is pulmonary angiography?
    study of the blood circulation leading from the right ventricle of the heart to the lungs and returning to the left atrium of the heart
  29. how much higher is the left pulmonary artery from the right pulmonary artery?
    1 cm higher
  30. what are the two main branches of the left pulmonary artery and what do they feed?
    • ascending and descending
    • feed the upper and lower lobes respectively
  31. the right pulmonary artery divides into what and what do they feed?
    • divides into an ascending branch which feeds the right upper lobe
    • divides into descending branches which feed the right middle and right lower lobes
