The human heart could compensate for flow rate changes to maintain blood pressure by setting the pace at which it beats and maintains blood flow. When a heart rate increases, blood pressure will rise, and when a heart rate decreases, blood pressure will drop.

What is the effect of hypovolemic shock on the blood vessels and the heart?
Blood vessels constrict to increase venous return and maintain pressure. Heart rate increases to compensate for loss of blood pressure and to maintain cardiac output.
If you feel dizzy and everything goes black?
What you were experiencing, in doctor speak, is orthostatic hypotension, a sudden drop in blood pressure. Normally, blood vessels constrict to maintain blood pressure and compensate for changes in position, but in some cases the blood vessels don't compensate and, when you stand up, the blood doesn't go to the brain. Basically, the reflexes of the body don't catch up with the blood vessels.
What do plasma proteins that remain in the blood capillaries help?
Maintain the osmotic pressure of the blood
Why is when sometimes you stand up everything goes black?

Can electric shock cause high blood pressure?
Not necessarily. Your body will try to compensate when it is in shock by raising the heartbeat (thereby increasing blood pressure). But sometimes the body can not compensate adequately. In this case, your blood pressure may not increase.
Why astronaut weigh less when they come back to earth?
When astronauts are floating in space due to the weightlessness effect their hearts do not have to work as hard to circulate blood and not as much blood is required to maintain their blood pressure. To compensate for this their bodies expel excess fluids while they're up there.
Which receptor in sensitive to changes in pressure?
Baroreceptors are sensitive to changes in blood pressure. The carotid sinus in the neck is one place where blood pressure is monitored and can be changed.
What is the baroreceptors?
Detects changes in blood pressure.
Which element help maintain healthy blood pressure?
magnesium
Plasma proteins that remain in the blood capillaries help to?
Maintain the osmotic pressure of the blood.
What does blood pressure 44 over 34 and pulse 128 mean?
Probably a large loss of blood. Not enough to keep the pressure up and the heart beats faster to try and compensate.
