Expert Solution
Step 1
The human heart is myogenic that means it can produce its own action potential. Different regions in the heart contain specialised cells that are responsible for producing electrical impulses that are conducted throughout the heart muscles and responsible for heart beating.
Those specialised cells that can produce electrical impulses are present in a specialised aggregation and form a node like structures.
