How does blood volume affect the flow of blood in the cardiovascular system?

Answer 1

My impression is that arterial blood pressure when within normal levels, flows without difficulties into the blood stream. When this normal level raises to a higher one, there is a narrowing in the blood vessels, making the blood circulation more slow and consequently overcharge the heart work, causing fatigue to that person and easing the formation of atheromas. Conclusively a normal blood pressure makes the blood circulation becomes more eficient, thus nourishing cells better. Hypertension is easily treated and cured on its initial stages.

Answer 2

Normal blood volume perfuses all organs.

Decreased blood volume causes a shift to major organs - brain, heart, lungs and kidneys, and a major decrease to all other areas. The heart must work harder to keep the major organs perfused with a constant flow of O2 and glucose to the brain and cells.

Increased blood volume puts stress on the heart, lungs, and kidneys, making the kidneys work harder to create homeostasis (a return to 'normal') by filtration and excretion.

Answer 3

The relationship between blood pressure and blood volume is an increase in blood volume causes high blood pressure. They are proportional to each other.

Answer 4

Cardiovascular function can increase the blood pressure. If the heart rate increases, blood pressure also does.

Answer 5

no increasing blood volume dosent increases blood pressure if a person is a marathon runner

running 42kms in 3hrs

Answer 6

Increasing the blood volume will increase the return to the heart which will increase the cardiac output. Increased cardiac output increase s blood pressure.
