    carries oxygenated blood from lungs to left side of heart
  47. saphenous veins
    longest veins located in lower extremities
  48. sinoatrial node (SA)
    heart's pacemaker located in right atrium responsible for coordinating heart contractions through atria
  49. sinus rhythm
    normal heartbeat originating from SA node
  50. stenosis
