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.

∙ 15y agoSystole refers to the ventricular contraction phase of the cardiac cycle. This is the most powerful part of the heart beat and causes the aorta to distend slightly.
Diastole refers to the relaxation and filling of the ventricles and release of stored energy in the aorta caused by its distension during systole.

How is pulse related to systole and diastole?
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.
What valve opens during systole?
aortic and pulmonic
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.
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.
The atrioventricular valves are closed during the entire period of?
ventricular systole
Is the blood pressure in systemic arteries greatest during atrial systole or ventricular systole?
ventricular systole
What is the contractive phase of heartbeat?
systole
Period of heart contraction?
Contraction of the ventricles and atria is called systole. Relaxation is called diastole.
What is the time taken by atrial systole and ventricular systole?
0.4sec
What is a contraction phase of the heartbeat?
The cardiac cycle of the heart has two phases - the diastole phase and systole phase. In the systole phase, the ventricles contract and pump blood into the arteries.
Who comes first atrial systole or ventricle systole?
Atrial systole -- The atrium contracts, then the ventricle.
What does the term systole mean?
Systole is the period of heart contraction within the cardiac cycle.
A diagram of the ventricular systole in the heart?
This can be seen by clicing on the link below ( The ventricular systole )
What are the two qualities of the heart beat which must be observed?
diastole and systole diastole and systole
What is the contraction of the ventricles?
This would be ventricular tachycardia (tachy - fast, cardia - heart). This is a life-threatening medical emergency that requires immediate care.
What is the stage of the heart cycle in which the heart muscle contracts and the chambers pump blood?
systole
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.
