The Purkinje Fibers Directly Cause the Contraction of the Ventricles

Question

The Purkinje fibers directly cause the contraction of the ventricles of the heart.

Accepted Answer

The Purkinje fibers are a specialized network of cells that conduct electrical impulses throughout the ventricles, which then cause the ventricles to contract and pump blood out of the heart. Therefore, the Purkinje fibers do directly cause the contraction of the ventricles.
