Systolic and diastolic contractions are two phases of the cardiac cycle that allow the heart to beat. During systole, the heart muscle contracts, pushing the blood out of the heart and into the arteries. This contraction causes an increase in pressure within the arteries. Following systole, during diastole, the heart muscle relaxes, allowing the chambers of the heart to fill with blood again. This relaxation phase also helps in refilling the coronary arteries with oxygenated blood. The alternation between systole and diastole generates the rhythmic beating of the heart, ensuring the continuous circulation of blood throughout the body.
