What is the time length for atrial diastole?
.7 seconds
What is the term that defines the relaxation phase of the heartbeat?
diastole
What is ventrical diastole?
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.
What is the relaxing phase of the cardiac cycle?
The resting phace of the cardiac cycle is known as the refractory period
What is the name for Blood pressure recorded during ventricular diastole?
diastole
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.
What heppens to artery when it is in diastole?
Diastole is when the artery is pushing the blood around the body
What is atrial diastole?
Atrial refers to the top portion of the heart and diastole is when the heart is at rest. Atrial diastole would be when the top portion of the heart is not beating.
What is the accented syllable for the term diastole?
Diastole is accented on the second syllable.
What coronary arteries fill with blood to deliver to heart during what phase?
diastole
What are the two qualities of the heart beat which must be observed?
diastole and systole diastole and systole
Why is the mean arterial pressure not calculated as systolic plus diastolic divided by 2?
This is because the lengths of systole and diastole are different. Usually in a resting individual having his or her blood pressure taken, the amount of time spent in diastole is longer than the amount of time spent in systole. The length of time the heart is in diastole is approximately twice as long as it is in systole. Systole only occurs when the heart is actively contracting, the rest of the time is diastole. So mean arterial pressure is usually closer to one's diastolic pressure than systolic. As one's heart-rate increases and the length of diastole shortens, the mean arterial pressure is much closer to just the average of systolic blood pressure and diastolic pressure.
