MICROANATOMY

Detailed explanation-1: -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.

Detailed explanation-2: -Cardiac cycle events can be divided into diastole and systole. Diastole represents ventricular filling, and systole represents ventricular contraction/ejection. Systole and diastole occur in both the right and left heart, though with very different pressures (see hemodynamics below).

Detailed explanation-3: -The correct option is A Systole and Diastole. The human heart works by contraction and relaxation of the cardiac muscles. The contraction phase is called systole and relaxation phase is called diastole.

Detailed explanation-4: -The contraction of ventricle is referred as systole. The stroke volume is also called as the blood which is ejected out from the ventricle when the left ventricle contracts for one time.
