n the given diagram, the role of ‘X’ is to A) Generate cardiac impulse B) Cause atrial systole C) Cause ventricular diastole D) Carry cardiac impulse to ventricles

Correct option:(D)Carry cardiac impulse to ventricles

Solution:

  • X is bundle of His.
  • Also called a atrioventricular bundle.
  • Bundle of many cardiac muscle fibers specialized in electric conduction.
  •  It carries and transmits cardiac impulses from AV node to ventricles.
  • Basically regulates the heartbeats from atrium to left and right ventricles.
