Diastole is the relaxation phase. Systole is the contraction phase.
If you put these phases together you have the Cardiac Cycle...

Period of heart contraction?
Contraction of the ventricles and atria is called systole. Relaxation is called diastole.
The Alternating expansion and contraction of walls caused by the contraction and and relaxation of the ventricles can be felt by your wrist?
What you feel in your wrist is a pulse. The pulse is caused by the heart pumping blood round your body.
What is the meaning of the two sounds of the heart?
relaxation and contraction of the heart
How do you call the contraction and relaxation?
Contraction and relaxation are two opposites. They work together when the muscles of the body work. A good example is the contraction and relaxation of the heart. The contraction allows blood to be distributed to the parts of the body while the relaxation allows the heart to be oxygenized and therefore fill up blood to be distributed to the whole body.
What allows the movement of blood in and out of the heart?
contraction and relaxation of the heart muscles
What allows the movements of the blood in and out of the heart?
contraction and relaxation of the heart muscles
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 layer of the heart is responsible for contraction and relaxation?
Myocardial layer
What are murmurs?
Those which occur during relaxation of the heart between beats are called diastolic murmurs. Those which occur during contraction of the heart muscle are called systolic murmurs
What is a complete cycle of a heart contraction and relaxation called?
Cardiac cycle, which is made up of atrial and ventricular systole and diastole.
Is the 2nd heart sound in the period of isometric contraction?
no. it occurs at the beginning of isovolumetric relaxation.
What are diastolic murmurs?
Those which occur during relaxation of the heart between beats are called diastolic murmurs. Those which occur during contraction of the heart muscle are called systolic murmurs
