The auricles will contract during the systolic phase of the cardiac cycle. This is one of the numbers that is measured when a patient has their blood pressure taken.
AV valves close during the systole phase of the cardiac cycle.
The ventricles relax during diastole.
The diastolic phase
The coronary artery fills during the diastolic phase of the cardiac cycle
The circulatory phase begins at 4 minutes and lasts through 10 minutes following the cardiac arrest.
Systole is the correct answer
ventricular diastole
Once the ventricles contraction phase is over, the diastole starts. Then all the four chambers are in diastole, till the atria start to contract.
AV valves close during the systole phase of the cardiac cycle.
Diastole is the relaxation phase. Systole is the contraction phase. If you put these phases together you have the Cardiac Cycle...
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.
diastolic
Systole
Atria Diastole is the longest (0.7sec)
Diastole is the phase in the cardiac cycle that allows filling of blood into the ventricle. It corresponds to the lower number in the blood pressure measurement. A normal upper limit of the blood pressure falls in the range less than 120/80 mm Hg. Above this value, it is considered pre-hypertension based on The Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure.During the diastolic period the ventricle is in the fifth phase of the cardiac cycle. This phase is termed isovolumetric relaxation which occurs immediately after the second heart sound. In this phase, all valves of the heart are closed. The volume of blood in the ventricle during this phase of the cardiac cycle remains constant. Following the fifth phase of the cardiac cycle is the rapid filling of blood into the ventricle. This cycle corresponds to the opening of the mitral and tricuspid valves located between the left and right atria and ventricle, respectively. The next phase of the cardiac cycle, called diastasis, is the longest phase of the cardiac cycle. In this cycle, the ventricle continues to fill with blood but at a much slower rate. The final phase of diastole corresponds to the first phase of the cardiac cycle. In this phase of the cardiac cycle, the atria contracts to provide additional filling of blood into the ventricle. After the final phase of diastole, the systolic phase of the cardiac cycle begins.
