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.
Systolic is when you heart muscle is relaxed and diastolic is when your heart muscle contracts.
Diastole. The origin of the coronary arteries are blocked by the semi-lunar leaflets of the aortic valve during systole.
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.
contraction phase and relaxation phase of the ventricles
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.
I have no idea:P
diastole and systole diastole and systole
I believe that is called diastole, in contrast to systole, the contraction of the heart muscles.
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.
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
Mid-to-late diastole, ventricular systole and early diastole
Diastole. The origin of the coronary arteries are blocked by the semi-lunar leaflets of the aortic valve during systole.
The terms systole and diastole most often apply to the Right and Left Ventricles
Myocardium
Contraction of the ventricles and atria is called systole. Relaxation is called 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

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).
