So this is found between the atria and between the ventricles of our heart. Now what this AV node does is it does two things. Firstly, once it actually receives that action potential from the essay node, it delays that action potential by about zero point twelve of a second. And the reason it creates this delay in electrical signal is because it wants to make sure that the two atria finish contracting and finish moving all that blood into our ventricles of the heart. So once the AV node receives that electrical signal, that AV node delays that signal before actually depolarizing. And once it depolarizes, it also creates its own action potential that then moves via specialized cardiac fibers called the bundle of his.
