Hi Denise,

Unfortunately some bad news.

If you look on:

http://www.sciencebuddies.org/mentoring ... tion.shtml

you'll notice that "Effect of running, music, video games, or almost anything on blood pressure" is listed as a topic to avoid. Please consult the page above for the reason. So you may need to pick a different topic.
Cheers!

Dave

Hi Whitney357, as I posted in your other topic:
Welcome to the Ask an Expert forums. These forums are for providing advice to high school students for their science fair projects - we do not have a medical staff for health related advice. I recommend that you ask a medical professional.
Thanks for asking, and sorry we can't help.

Regards,
Chris

Hi whitney357,

Just curious, what is "BG" in Occupation: BG?

Thanks.
Cheers!

Why is blood pressure relatively more important than flow? Why is blood pressure more important than flow. For instance, you can have a lot of blood that will flow through an artery, but that is not good enough, it must also be a certain pressure. Indeed pressure is almost more important than the absolute amount of blood that flows. Can anyone explain why this is true?

Why is blood pressure relatively more important than flow?
I could easily take either side in a debate on this one. Bottom line, both flows and pressures are important. Within nominal pressure ranges, the specific pressures at different points in the circulatory system affect capillary function and how flow rates are balanced between competing paths. When pressures get too high, capillaries break. When pressures are too low, flows cease in smaller cross section portions of the system. When differential pressure (difference between systolic and diastolic pressure) is too low, the check valves in the system fail to prevent reverse flows. if this is insufficient for your purposes, please post a new question in the life science forum for the appropriate grade level.
