Blood can only enter an artery, be it the aorta, when the left ventricle contracts, or the pulmonary arteries, when the right ventricle contracts, which both occur at the same time after ventricular systole which is contraction. Therefore, the answer is contract.
1. Systolic Pressure
2. Diastolic Pressure
Measurements:
Systolic/Diastolic Pressure
1. Optimal Normal <120/80
2. Normal <129/88
3. High Normal <139/98
4. High Pressure <148/108
diastolic pressure
Pulse!
The force of blood when the ventricles contracts is called systolic. On the contrary, the force of the blood when the ventricles relaxes is called diastolic.
It is moving in the arteries toward the rest of the body.
The diastolic blood pressure is when the heart is relaxed and filling.
Diastolic pressure
systolic
The heart chambers are called atria and ventricles. Arteries and veins are blood vessels.
The heart chambers are not called arteries and veins. Heart chambers are atria and ventricles.
Arteries carry blood away from the heart.
There are several different stages in the heart cycle at which different parts of the heart relax, but people are most often concerned about this as it pertains to blood pressure. In that case, the diastolic pressure is when the heart is relaxed.
Diastolic pressure
The first number is called your systolic blood pressure and the second is called your diastolic. The Systolic is the pressure in your arteries when the ventricles are contracting - so it is the maximum pressure that the heart exerts on the arteries. The diastolic is the pressure when the heart is relaxed - so it is the minimum amount of pressure.
The heart chambers are called atria and ventricles. Arteries and veins are blood vessels.
The heart chambers are not called arteries and veins. Heart chambers are atria and ventricles.
No, they are called atria and ventricles...you have two of each
Contraction of the ventricles and atria is called systole. Relaxation is called diastole.

The term is 'diastolic pressure' I think u know that our heart contracts & relaxes. The term 'diastole' refers to the state of the relaxation of the heart (specially ventricles). During diastole of the heart the ventricles draw blood. As a result the blood pressure falls. The minimum blood pressure during the diastolic state of the heart is called the diastolic pressure. It is about 60-90 mm Hg (average 80 mm Hg) in a healthy adult person.
When after contraction of ventricles of heart, blood is propelled into circulatory system (both systemic and pulmonary circulation) and that pressure is called systolic pressure, witch dilates the aorta and large(and small also) arteries. When ventricles relax in diastole aortic (and pulmonary) valves close down and then aorta and large (and small also)arteries contract, witch are dilated during systole. Peripheral resistance in closed system maintain the lower blood pressure called diastolic blood pressure.
