What is syatole |
|
Answer» Systole is the contraction of heart chambers, driving blood out of the chambers. Systole is initiated by the sinoatrial node, which is the heart\'s natural pacemaker. These cells are activated spontaneously by depolarization of their membranes. During systole, blood is driven through the aorta and pulmonary artery after each dilation or diastole.Diastole is the period of time when the heart relaxes after systole.\xa0 Systole is the contraction of heart muscles. |
