What Is Contraction of Heart Muscle Called

The contraction of heart muscle is commonly referred to as systole. This term comes from the Greek word “sustellein,” which means to contract or draw together.

During systole, the heart muscle contracts, pushing blood out of the chambers and into the circulatory system. This is an essential part of the cardiac cycle, as it ensures that oxygen and nutrients are delivered to the body`s tissues and organs.

In contrast, diastole is the relaxation phase of the cardiac cycle, during which the heart muscle relaxes and refills with blood. Together, these two phases make up a complete heartbeat.

It`s important to note that there are different types of systole, depending on which part of the heart is contracting. For example, atrial systole refers to the contraction of the atria, while ventricular systole refers to the contraction of the ventricles.

Understanding the mechanics of systole and diastole is key to diagnosing and treating cardiovascular diseases. Medical professionals may use tools like echocardiograms and electrocardiograms to monitor the heart`s activity and identify any abnormalities.

In summary, systole is the contraction of the heart muscle that forces blood out of the chambers and into the circulatory system. It`s a critical component of the cardiac cycle and plays a fundamental role in maintaining overall health and well-being.
