Diastole is the relaxation phase. Systole is the contraction phase.
If you put these phases together you have the Cardiac Cycle...
Systole and Diastole
That is called the heartbeat.
cardiac cycle
Contraction of the ventricles and atria is called systole. Relaxation is called diastole.
What you feel in your wrist is a pulse. The pulse is caused by the heart pumping blood round your body.
relaxation and contraction of the heart
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.
contraction and relaxation of the heart muscles
contraction and relaxation of the heart muscles
I believe that is called diastole, in contrast to systole, the contraction of the heart muscles.
Myocardial layer
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
Cardiac cycle, which is made up of atrial and ventricular systole and diastole.
no. it occurs at the beginning of isovolumetric relaxation.
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
