It is called the systolic blood pressure and is given by the higher of the two numbers on your blood pressure reading. eg, if your blood pressure is 120/80, the systolic pressure is 120mmHg.
The actual pressure follows a wave-form. As the ventricle contracts and squeeze blood into the arteries the pressure rises (from the lower diastolic level) and as contraction continues the pressure peaks and then drops back as the contraction finishes and the heart begins to relax. So to be specific the pressure will depend upon what phase of contraction one is referring to. However generally speaking it is the peak, as explained above, that is referred to.
Its called contraction,
the reason is the same as in a bicycle pump.

Systolic
True
systolic to diastolic
No. I think the systolic pressure is when ventricles constrict and the blood goes out , while the diastolic pressure is when ventricles relax and fill with blood.
Diastolic pressure
No, they're aren't any valves in the arteries.
The ventricles contract and force the blood under pressure, past the semi lunar valves into the arteries. The closing of the bicuspid and tricuspid valves prevents back flow. At the same time the atria and ventricles relax and blood begins to flow back into them from the veins.
Blood pressure is not made up of chambers. Blood pressure measurements include the systolic number, indicating the higher pressure when the ventricles contract, and the diastolic pressure, the pressure when the ventricles relax.
The ventricles relax during diastole.
blood is pushed against the semilunar valves, causing them to close
Blood pressure is the force of blood against the inner walls of arterial blood vessels. Blood pressure rises when the ventricles contract and falls when the ventricles relax. Systolic pressure is the maximum pressure and diastolic pressure is the minimum pressure.
When relaxed, the atria expand, and then the ventricles contract.
The QRS complex causes the ventricles to contract. This has to happen before they can relax.
