∙ 12y agoThis is the circulation of blood to the myocardium, or heart muscle, to supply oxygen and to remove CO2 waste just as any other cell requires. It is the same process as is circulation to any other part of the body. Coronary arteries bring oxygenated blood from the left ventricle and diffusion of the oxygen into the myocardial cells occurs in the coronary capillaries, which have narrowed from arteries to arterioles to capillaries. As in all capillary circuits, the venus end picks up CO2 and then become coronary venules and coronary veins, emptying into the vena cava like all veins do, to bring the blood to the right side of the heart where it is pumped to the lungs to discharge the CO2 and pick up more oxygen, returning through pulmonary veins to the left atrium and ventricle to begin the circuit again.

What is a cardiac cycle?
Cardiac cyccle is the term referring to all of the events related to the flow of blood that occur from the beginning of one heartbeat to the beginning of the next. The frequency of the cardiac cycle is the heart rate.
What initiates the p wave?

Is the Cardiac muscle appears striated and is completely voluntary?
cardiac muscle is striated cardiac muscle is not voluntary
What is the duration of the cardiac cycle?
It depends on the heart rate. You take 72 beats per minute. Then the duration of one beat is 75 per minute. Then each beat will take 0.8 second to complete. This is taken duration of the cardiac cycle. You take 100 beats per minute. Then each beat will take 0.6 second to complete. This duration will be the duration of the cardiac cycle.
Which phase of the cardiac cycle is longest?
ventricular diastole
