ANATOMY

Detailed explanation-1: -Diastole begins with the closing of the aortic valve (or pulmonic) and ends with the closing of the mitral valve (or tricuspid). This period encompasses the ventricular relaxation and filling. Diastole represents when the blood vessels return blood to the heart in preparation for the next ventricular contraction.

Detailed explanation-2: -Diastole-this period of time when your heart relaxes between beats-is also the time that your coronary artery is able to supply blood to your heart.

Detailed explanation-3: -Generally, diastole is longer than systole. The duration of diastole also depends on stress. Diastolic time increases during stress due to high pulse rates.

Detailed explanation-4: -The cardiac cycle is essentially split into two phases, systole (the contraction phase) and diastole (the relaxation phase). Each of these is then further divided into an atrial and ventricular component.

Detailed explanation-5: -Systole is the phase when the heart contracts. During this phase, it squeezes out blood to the rest of the body. Diastole is the phase when the heart relaxes. During this phase, it fills up with blood to prepare for its next beat.
