Across
  1. 4. left branches that transmits electrical impulses from bundle of His through left ventricle
  2. 6. mass of tissue that transmits impulses from SA node to ventricles via bundle of His
  3. 9. to contract, atria and ventricles depolarize when heart beats
Down
  1. 1. right branch that transmits electrical impulses from bundle of His through right ventricle
  2. 2. transmits impulses throughout ventricles that causes ventricular contraction
  3. 3. muscular bundle that connects left and right atria
  4. 5. bundle of cardiac muscle that conducts electrical impulses from AV node to left and right bundle branches to Purkinje fibers in the ventricles
  5. 7. specialized tissue in the right atrium that acts like the pacemaker (60-100bpm)
  6. 8. to relax, atria and ventricles repolarize when heart beats
