Final answer:
The continual recycling of electrical waves through the myocardium is called the cardiac cycle. It consists of the rhythmic contraction and relaxation of the heart chambers, ensuring efficient blood flow throughout the body.
Step-by-step explanation:
The continual recycling of electrical waves through the myocardium is called the cardiac cycle.
The cardiac cycle consists of the rhythmic contraction and relaxation of both the atria and ventricles, which is vital for effectively pumping blood throughout the body.
During the cardiac cycle, the heart undergoes systole (contraction) and diastole (relaxation) to ensure efficient blood flow.
The electrical signals that initiate and coordinate the cardiac cycle are generated by the heart's internal pacemaker cells, which cause sequential contraction of the heart chambers.
