A bundle of modified heart muscle fibres (Purkinje fibres) passing from the atroventricular node forward to the septum between the ventricles, where it divides into right and left bundles, one for each ventricle, The fibres transmit contraction waves from the atria, via the AV node to the ventricles
A group of cells in the heart located between the upper two chambers (the atria) and the lower two chambers (the ventricles) that regulates the electrical current that passes through it to the ventricles
Atrioventricular valves are the two valves that control blood flow from the atria (the heart’s upper chambers) into the ventricles (the lower chambers), preventing backflow. The mitral valve lies between the left atrium and left ventricle, and the tricuspid valve lies between the right atrium and right ventricle. Together with the arterial (semilunar) valves at … Read more
