There are several different stages in the heart cycle at which different parts of the heart relax, but people are most often concerned about this as it pertains to blood pressure. In that case, the diastolic pressure is when the heart is relaxed.
The relaxation phase of the heart cycle is called diastole, or the diastolic phase.
Following systole, diastole is the period when the heart fills with blood. The ventricles (lower chambers) are relaxing and your blood pressure drops.
Diastole is the relaxation phase of the heart.
during diastolic phase the chambers of heart get filled with blood systolic phase and diastolic phase are the phases oh heartbeat and diastolic phase is also known as resting phase.
The diastolic phase
The ventricles of heart have two states: systole(contraction) and diastole (relaxation). During diastole blood fills the ventricles and during systole the blood is pushed out of the heart into the arteries. The auricles contract anti-phase to the ventricles and chiefly serve to optimally fill the ventricles with blood.http://www.answers.com/systole
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.
Diastole is the relaxation phase. Systole is the contraction phase. If you put these phases together you have the Cardiac Cycle...
The relaxation phase of the heart is when there is no compression pressure on the heart.
Diastole is the relaxation phase of the heart.
Diastole
diastole
That phase is called as isovolumetric contraction phase.
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.
closed and closed
Heart systole refers to the phase of the cardiac cycle when the heart muscle contracts to pump blood out of the chambers (ventricles) into the circulatory system. This contraction leads to an increase in blood pressure within the arteries, pushing blood to the rest of the body. Systole is typically followed by diastole, the relaxation phase of the heart.
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.
it is pumped out of the lungs
during diastolic phase the chambers of heart get filled with blood systolic phase and diastolic phase are the phases oh heartbeat and diastolic phase is also known as resting phase.
