From what depends a pressure?

 In a young human pressure is having to be 120/80 , in adult a same, or more? I was born on 1946 , my pressure is 140/76 /72/, if am I checking on the left hand, but on the right 163/82/75/ Why is here different  happening?

Are you right, pressure checking? His check on arteries, pinch theirs, after check a beginning and end pulsation with tonometer, or sphygmomanometer,  a how this still calling such preparation. But on results affecting a lot. Check pressure need a one hour till meal, physical loads, smoking, coffee. Pressure   depends on from a nerve and hormonal systems, thus within a day he is changing. And on the sleep his stats are low, and on the stress, waggling  and stress is vice versa. . A lot depending on and from you emotional condition. Emotions are lead to ejection in blood hormone stress is adrenaline,which manufacturing my adrenalin, in result heart beating faster, and pressure in vessels rising. And on results for check and other anti stress hormone for adrenals is cortisol. A before to say about hypertension, thus you need to know what is hypertension. Is a common blood pressure in arteries, and he is different, in depend on from a size and throw away from a heart. And a most close arteries to the heart ,thus she is widely, and higher in here a pressure.And a most high pressure  in aorta as a most  big artery, and importance, which comes out from a heart, from a left ventricle. Lots of us knew,that normal  stats for pressure  are 120/80 , but these stats say, a which pressure in your shoulder waist,data stat taken for base , therefore on a shoulder artery is easy check pressure.. You know,that a first number,received of checked  a top /heart/ pressure, second is low/kidney/, and this is a true. A top pressure 120 mm reflects, with a which force  a heart pushes out blood in artery. And usually considered,that  a most often heart beat, thus a higher  pressure in arteries. But a not an always. In shock conditions,when pressure faster lowering , heart beating often, but in arterial hypertension a frequently for heart beatings is usually  high. A low limit as on 80 mm reflects a tone for blood vessels, on which affects kidney work, and if a patient having kidneys problems,thus this index is rising.Especially if secreting a much renin  is biologic active substance,which  affects on a tone vessel walls, thus a groups for remedies for hypertension works,like a blockage renin. But in every human is an own working pressure and his need to know.With age,  pressure stats are differencing from numbers 120/80 plus -minus 10-20 units.This importance to know in hypertonic crisis.
