Systole is when the heart muscle contracts.

When the heart contracts, it pushes the blood out of the heart and into the large blood vessels of the circulatory system. From here, the blood goes to all of the organs and tissues of the body.

During systole, a person’s blood pressure increases.

Diastole is when the heart muscle relaxes.

When the heart relaxes, the chambers of the heart fill with blood, and a person’s blood pressure decreases.

Systole Diastole

1 It is the contraction of the heart chambers to drive blood into the aorta and the pulmonary artery. The aortic valve and the pulmonary valve remain closed during the systole while the semilunar valves remain open. It is the relaxation of the heart chambers between two contractions. During diastole, the chambers are filled with blood. The filling of the atrial chamber is known as atrial diastole and filling of the ventricles is known as ventricular diastole.

2 Systole decreases the volume of the heart chambers and forces the blood out of them.

Diastole brings the heart chambers back into their original sizes to receive more blood.
