What is systole?
A
phase of the heartbeat when the heart muscle contracts and pumps blood from the chambers into the arteries.
B
the atria and ventricles relax and fill with blood
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -Systole (left) typically refers to ventricular systole, during which the ventricles are pumping (or ejecting) blood out of the heart through the aorta and the pulmonary veins.

Detailed explanation-2: -There are 2 phases to your heart’s pumping cycle: systole – this is when your heart contracts, pushing blood out of the chambers. diastole – this is the period between contractions when the muscle of your heart (myocardium) relaxes and the chambers fill with blood.

Detailed explanation-3: -During systole, the blood vessels are distended by the heart forcing blood from the ventricles into the systemic (or pulmonic) system. This energy is stored in the blood vessel walls like an elastic tube.

Detailed explanation-4: -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-5: -Systole is the contraction phase of the heartbeat. During this phase, the right and left ventricles contract to pump blood to the lungs and body. Blood pressure measures pressure during both ventricular contraction (systolic pressure) and during relaxation (diastolic pressure).
