Physics....please help?

Question

Please help me I am completely lost with this problem....

Explain how to reduce high blood pressure and the physics of why it works?

Answer 1

Well i dont know but this is how i think:

You must have been asked to reduce salt intake.... to reduce high bp....

here is the physics behind it

Salt is an electrolyte... when an electrolyte is added to a solution, its water potential becomes more. If two solutions are separated by a semi-permeable membrane; water from the solution with less water potential comes to the solution with more potential.

Salt increases potential of your blood ... and thus water from cells (separated from blodd by the semi-permeable cell membrane) .... comes to the blood.... thus the water pressure (hydrostatic pressure) of blood increase (since water content increase....)


well.... if i think of other things i will tell here (edit my post) .. .and even if u think of something keep me updated ....

Answer 2

1) Reduce pump work (alpha- and beta-blockers).
2) Reduce pumped volume (diuretics).
3) Reduce plumbing serial length (weight loss).
4) Reduce peripheral resistance (vasodilators).
5) Reduce pumped fluid viscosity.
6) Reduce spring constant of elastic tubing.
7) Increase tubing bore and paralellism (exercise)

Answer 3

One way is to cut out salt in your food. Osmotic pressure will cause the water to diffuse out of your cells and into your blood because of the concentration difference sue to the salt in your blood. The more water in your blood the higher your blood pressure.
