the purkinje fibers are responsible for sending the electrical impulse into which area of the heart?
the myocardium of the ventricles
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 ( ) (purkinje tissue or subendocardial branches) are located in the inner ventricular walls of the heart, just beneath the endocardium in a space called the subendocardium. the purkinje fibers are specialised conducting fibers composed of electrically excitable cells that are larger than cardiomyocytes with fewer myofibrils and a large number of mitochondria and which (cells) conduct cardiac action potentials more quickly and efficiently than any other cells in the heart. purkinje fibers allow the heart's conduction system to create synchronized contractions of its ventricles, and are, therefore, essential for maintaining a consistent heart rhythm.
