Describe the components and conduction pathway of the cardiac conduction system of the heart.

The flow of blood through the heart and body is driven by contractions of the heart chambers. These contractions are activated by the cardiac conduction system.

. Describe the components and conduction pathway of the cardiac conduction system of the heart. Relate the cardiac conduction system to the corresponding sequence of heart chamber contractions

Trace the pathway of oxygen delivery to cells in the body (commencing at the alveoli until it reaches tissue cells)

. Describe one normal age-related change to the anatomy of the cardiovascular system in healthy elderly adults (over 65 years). Describe how this change affects the function of the cardiovascular system.
