Expert Solution

Step 1

The heart is responsible foe pumping of blood in the body. The blood is pumped due to rhythmic contractions of the specialized contractile and conducting muscle cells in the walls of the heart. The action potential patterns of different cell types varies because of their specific contribution to the contractions. An action potential is generated because of movement of ions across the membranes of these specialized cells.
