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.
what is held when the pressure at the lungs increase and id it reach about 58and 40 which is high then the normal position
yes. because it pumps blood to the lungs.
it's a pulmonary VEIN because the blood isn't under as much pressure (because it has yet to get to the heart) where as the pulmonary artery is coming straight from the heart so is under more pressure. (the pressure is caused by the heart's contractions)
The blood vessels that take oxygenated blood from the right ventricle to the lungs are the pulmonary artery. It is part of the pulmonary circulation.

Systolic.
The systolic and diastolic pressures are the pressure exerted against the artery walls. This will vary from person to person. There is no one answer to your question.

normal ones
This is impossible. Systolic pressure is the pressure in the artery during the heart contractions. Diastolic pressure is during heart relaxation. Picture this, and you'd see that it's impossible to have diastolic pressure equal or greater than systolic pressure.
what is held when the pressure at the lungs increase and id it reach about 58and 40 which is high then the normal position
Yes, the wall of the pulmonary artery contains a layer of smooth muscle to deal with the high pressure from the heart, and to help push the blood along.
The pressure in the pulmonary artery increases during exercise if the cardiac output increases.
