After squeezing through capillaries, blood is no longer significantly pressurized by the heart. The pumping action that returns it to the heart is created by a combination of one-way valves in the veins and body movement. The valves prevent blood from flowing backward, and ordinary flexing of muscles and body puts pressure on changing parts of the venuous system. Where there is pressure from the surrounding tissue, veins are squeezed; blood, unable to flow back, flows towards the heart.
If you sit without moving for long periods of time, blood will pool in your legs and cause real problems. Fighter pilots with no room to move legs had to wear special suits that would squeeze their legs to pump blood.

What types of heart disease cause a weak heart and low blood pressure?
stroke
What heart problems can cause dizziness?
Low blood pressure or low oxygen saturation (%).
What does it mean when systolic pressure is high and diastolic is low?
Whereas Systolic pressure means the peak in blood pressure when your heart contracts, Diastolicpressure is the pressure when your heart relaxes, between beats.Low diastolic pressure usually means a low total volume of blood in the vascular system for the heart to pump. The most common causes of this would be dehydration or hemorrhage.
What are the solution to low blood pressure and high heart rate?

Low blood pressure but high heart rate?
low blood pressure causes what is called [reflex tachycardia] where the body realize that not enough blood is reaching the cells, so it stimulates the heart to beat more quicker
Does low heart rate mean low blood pressure?
because if your blood pressure is low then your heart isn't giving enough pressure I think
How does blood circulate around the lower arm and hand?
Blood pumps down and through the vessels in your hands by the pressure your heart pumps the blood from your heart. When you blood pressure is low then the blood isn't pumping with enough pressure.
What types of heart disease cause a weak heart and low blood pressure?
stroke
What does a distolic pressure of 35 mean?
The pressure of blood returning to the heart; 35 is low.
What heart problems can cause dizziness?
Low blood pressure or low oxygen saturation (%).
What is low blood volume called?
Low blood volume will cause low blood pressure, high heart rate as the heart tries to compensate. Eventually if the volume is low enough the person will go into hypovolemic shock.
Do arteries have low pressure?
No, arteries have high pressure as they carry blood from the heart to the rest of the body.
What does it mean when systolic pressure is high and diastolic is low?

If heart baet is high so is it necssary that blood pressure should also be high?
No not always. If someone is bleeding badly for example their blood pressure will be low but heart rate high as a compensation. Blood pressure and heart rate are usually inversly related.
What neurotransmitter causes low blood pressure?
The neurotransmitter epinephrine can cause the blood pressure to become low. This neurotransmitter also regulated the heart rate. It is often controlled by stress.
Why is it important to measure the blood pressure?
High blood pressure or hypertension can be an acute problem. The heart muscle enlarges and can become weaker over time. Hypertension is one of the risk factors for strokes, heart attacks, heart failure, and renal failure. Low blood pressure or hypotension can cause decreased blood supply to the brain and shock. Other causes of low blood pressure or hemorrhage, sepsis, and toxins.
