Systole and diastole most often refer to the ventricle of the heart. Systole is contraction of the ventricle, and diastole is the relaxation of the ventricle.
Systole is when a chamber of the heart (i.e. atrial vs. ventricular systole) is contracting. Diastole is when a chamber of the heart is relaxing. Without qualifying which chamber it is usually assumed to mean the left ventricle.Systole refers to when the heart is contracted and diastole refers to when the heart is relaxed.
The terms systole and diastole most often apply to the Right and Left Ventricles
This is called systole. When the heart chambers relax, it is called distole. I hope that this helps you out!
the ventricles
No, diastole is the period when a particular chamber of the heart relaxes. the highest pressure period is during systole.
diastole and systole diastole and systole
I think systole is when the heart contracts- the "lub" of the heart- and diastole is when the heart relaxes- the "dub" of the heart. Systole is the numerator of the fraction and diastole is the denominator of the fraction. Ex. 120/80 120 is systole and 80 is diastole
I believe that is called diastole, in contrast to systole, the contraction of the heart muscles.
Diastole is when a given chamber of the heart is relaxing. There is atrial diastole and ventricular diastole. Most of the time when talking about diastole we are referring to the ventricular because that is when we measure the diastolic (low) pressure in your systemic arteries, usually the brachial artery.
Systole and diastole describe the phase/state the heart is in during a heartbeat. Systole refers to the heart when contracted, and blood is pumped into the arteries. Diastole refers to the heart when it is relaxed and blood enters the upper chambers.
The heart spends more time in diastole.
Contraction of the ventricles and atria is called systole. Relaxation is called diastole.
