according to bernoulli's principle and just like BP vs. vasodilation.... when the pipe gets bigger (dilation) the pressure goes down. just like putting ur thumb over the end of a garden hose thusly decreasing the size of the pipe the pressure skyrockets.

When the Arteries dilate they become bigger. When the become bigger the blood has less resistance and so your blood pressure goes down.

Does oxygen dilate blood vessels?

No, oxygen does not dilate blood vessels. In fact, oxygen has a vasoconstrictive effect, which means it causes blood vessels to constrict or narrow. This helps regulate blood flow and pressure in the body.

Why does blood pressure decrease after long term exercise?

Yes your blood pressure will decrease for a couple of different reasons: The first is that your blood vessels have dilated to provide muscles with an increase in oxygenated blood and the surface (peripheral blood vessels) will dilate to increase the rate of heat loss from the body. Over a sustained period of exercise (months) the blood vessels will become more elastic, decreasing the pressure on the vessel walls and more importantly on the left ventricle of the heart. There will be a similar decrease in your resting heart rate. Overall your cardiovascular system will become "younger".

Conditions causing high systole and low diastole?

If your blood vessels dilate whithout an increase in your heart rate, your blood pressure can drop dramatically. exercise stimulates your heart rate to increase and also hormones such as Nitros oxide (NO aka. Viagra) causes vasocontriction or the contracting of blood vessels so that blood pressure rises.
