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.

Do coronary arteries get their blood supply during systole or diastole?
Diastole. The origin of the coronary arteries are blocked by the semi-lunar leaflets of the aortic valve during systole.
What is systole and diastole?
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 terms systole and diastole refer respectively to the?
contraction phase and relaxation phase of the ventricles
What do systole and dystole represent?
Systole - The time period when the heart is contracting. The period specifically during which the left ventricle of the heart contracts. Diastole - Referring to the time when the heart is in a period of relaxation and dilation.
What occurs during the time between the first heart sound and the second sound a. systole d. a heart mur mur b. diastole e. the p wave of the ecg c. ventricular filling?
I have no idea:P
What are the two qualities of the heart beat which must be observed?
diastole and systole diastole and systole
The contraction of the ventricles is referred to as systole and the period of ventricular relaxation is called?
I believe that is called diastole, in contrast to systole, the contraction of the heart muscles.
Which heart chamber do the terms systole and diastole most ofter apply?
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.
Why can you only feel one pulse and the doctors can hear two?
When a doctor listens to your heart he hears the systole and diastole of the heart. The "lub-dub" that they hear is the closure of valves of the heart at rest (diastole) when the heart fills with blood and the heart squeezes blood (systole) out into the body. When you feel the pulse, you only feel when the heart pushes blood through the vascular system during systole.
What is systole and diastole and how this relates to the two figures obtained when blood pressure is taken?
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
What are the phases of the cardiac cycle?
Mid-to-late diastole, ventricular systole and early diastole
Do coronary arteries get their blood supply during systole or diastole?
Diastole. The origin of the coronary arteries are blocked by the semi-lunar leaflets of the aortic valve during systole.
To which heart chambers do the terms systole and diastole usually apply?
The terms systole and diastole most often apply to the Right and Left Ventricles
Systole and diastole describe the function of the?
Myocardium
Period of heart contraction?
Contraction of the ventricles and atria is called systole. Relaxation is called diastole.
What is meant by systole and diastole?
The ventricles of heart have two states: systole(contraction) and diastole (relaxation). During diastole blood fills the ventricles and during systole the blood is pushed out of the heart into the arteries. The auricles contract anti-phase to the ventricles and chiefly serve to optimally fill the ventricles with blood.http://www.answers.com/systole
What is s1s2?
S1 S2 are heart sounds. The S1 sound occurs at the beginning of systole (end of diastole). The S2 sound occurs at the beginning of Diastole (end of systole).
