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

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.
