Different Phases of the Cardiac Cycle

The cardiac cycle's two primary phases can be recognized easily through Online videos of phases of the cardiac cycle. Systole is the term used to describe the first phase of the process, and diastole is the second. By watching these Online videos of the heart's different stages, a person will know how the heart works.

Two major parts of the heart:

The two major parts of the heart are the atria and ventricles, and they occur in order. Each part has several activities that move the heart through the cardiac cycle. Atria (or simply atriums) are located in front of the ribs. Ventricles are situated below the atria and can be found in the groin or pelvic regions.

The difference between systole and diastole is that systole occurs when the heart pumps blood continuously to the right side of the body, while diastole occurs when the heart pumps blood to the left side of the body. Another distinction is that when the atria are pumping blood into the right side of the body, ventricular dilation occurs, and the blood is pumped into the lungs. When the atria are pumping blood to the left side of the body, ventricular dilation does not occur. As you can see, the two processes go hand in hand.

Systole and daistole:

Online videos of the heart show the heart's major pumping activities during each of its two phases. Systole (the first of the two main phases of the cardiac cycle) lasts from a few seconds to about two minutes. Diastole lasts from about two to five seconds and maybe a couple of beats longer. You can see how much pumping activity the heart must have during each of these two phases.

The other two main phases of the cardiac cycle happen at a much faster pace. Systole may last only a second or two, and the ventricles may contract for only a moment. Ventricular dilation occurs much quicker during the first beat of each beat of the ventricular cycle. Once the second comes to an end, the ventricles start contracting again, and the cycle continues until the breath stops. This is why the heart seems to be "singing" during breathalyze.

Why heart stops functioning:

The atria are responsible for filling the chest cavity with blood as it is pumped to the lungs. Once the atria have filled the chamber, the cycle continues with ventricle contraction. The atria also hold the blood in the chamber until the hearts demand it. This is when the heart stops functioning. At this stage, the atria are not pumping blood to the lungs during the pumping phase of the cycle. As you can see, the ventricular and atria cycle rates' variations significantly alter the blood flow throughout the body.

As we have mentioned before, the atria are the muscle in our body that actually causes the heart to beat. The atria's job is to pump the blood through the body in the form of oxygenated blood. Without the atria, there would be very little oxygen in the blood. The heart would eventually stop beating. The atria also control how fast the heart is able to beat. Faster beat rates indicate a quicker heart.


Understanding the different cardiac cycle phases is essential if someone wants to make some improvements in their health. Each of these phases of the cardiac cycle has its own specific benefits. If you are having problems or are unsure of whether your heart is doing the right thing, make sure to talk to your doctor about it. Also, if you notice any irregularities in your heartbeat or pulse, you need to go check it out. By knowing what is going on with your heart, you can be better prepared for whatever the future brings.
