Concept 4: Heart Pump Operation

The activity of the conduction system, muscles, and valves of the heart are synchronized so that the heart can operate as a pump.

  • The conduction system initiates and coordinates the muscular activity of the heart.
  • Pressure differentials that result from muscle activity actuate the opening and closing of valves.
  • The opening and closing of valves directs the flow of blood through the heart.
