 
 <translate> During the ventricular contraction portion of the cardiac cycle, the Purkinje fibers carry the contraction impulse from both the left and right bundle branch to the myocardium of the ventricles. This causes the muscle tissue of the ventricles to contract and generate force to eject blood out of the heart, either to the pulmonary circulation from the right ventricle or to the systemic circulation from the left ventricle.

The purkinje fibers are responsible for sending the electrical impulse into which area of the heart? OK. Let's think. My stream of consciousness: <ibo> N'oge nkwekọrịta nke ventricular nke usoro obi, eriri Purkinje na-ebugharị nkwekọrịta nkwekọrịta site na alaka aka ekpe na aka nri nke aka ekpe na myocardium nke ventricles. Nke a na-eme ka uru ahụ nke ventricles na-agbakọta ma na-emepụta ike iji chụpụ ọbara site n'obi, ma ọ bụ gaa n'ọbara na-agagharị agagharị site na ventricle aka nri ma ọ bụ gaa n'ọbara na-agagharị agagharị site na ventricle aka ekpe.  Mkpụrụ ndụ Purkinje na-ebute ike eletrik n'akụkụ obi dị aṅaa? Ọ dị mma. Ka anyị chee echiche. Ihe m na-echeta:
