During a diastole, the blood pressure momentarily increases.
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
The first part of the cardiac cycle is called diastole, which is when the heart relaxes and fills with blood. This is followed by systole, when the heart contracts to pump blood out to the body.
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.
Diastole.
I believe that is called diastole, in contrast to systole, the contraction of the heart muscles.
Diastole is the relaxation phase of the heart.
The relaxing phase of the cardiac cycle is called diastole. During diastole, the heart chambers (atria and ventricles) relax, allowing them to fill with blood. This is followed by the contracting phase called systole.
In a normal individual, disatolic BP should remian unchanged (or decrease only slightly) as heart rate increases.
Diastole. It is the resting Phase. The Heart Chambers fill with blood. (Systole is the working or contracting Phase)
The relaxation phase of the heartbeat is called diastole. During diastole, the heart ventricles relax and fill with blood in preparation for the next contraction.
Diastole is when the muscles of the atria and ventricles relax and blood flows into the heart.Ventricular diastole is when the muscles of the ventricles relax and blood flows into the heart. N.B It is called ventricular diastole and not ventrical diastole.
Systole refers to the phase of the heartbeat when the heart muscle contracts and blood is pushed out of the heart chambers. Diastole refers to the phase when the heart muscle relaxes and the heart chambers fill with blood.
