Your final point on arteriosclerosis really made this concept meaningful to me. This is very helpful to learn why in fact blood pressure must be increased.
Thanks Charles, glad to hear it. I agree with you, its always so much more meaningful to describe a given equation in terms of something that is actually applicable and tangible.
I have a question, hoping you could help me please... Our professor said that Poiseuille's law applies to Newtonian fluids (which blood is not), flow through a stable cylindrical tube (blood vessels are not stable) and you need of course a stable flow. Now in order to use Poiseuille's law in blood flow we make some admissions. What admissions though? I mean how is blood considered Newtonian for example? Or how do you consider veins "stable"? Thanks in advance!
You explained the concept really well. Thank you. However my professor say that blood flow occurring in real life deals with a radius that is raised to the third power, rather than what is stated in the Poiseuille's Equation (r^4). Could you explain why?
in every equation there is atleast one independent to make that eq valid. what is independent factor in this equation.possibly initial pressure exerted by heart .2nd pressure is dependent on resistance (l/r4).plz correct me. if im wrong
Why do blood flow and blood pressure decrease when the protein content (therefore blood viscosity) in the blood increase (in accordance to the Hagen-Poiseuille equation)?
proteins in the blood will restrict the blood flow, therefore blood viscosity increases, blood flow decreases. and the "blood pressure" that you mention is actually the pressure gradient. the proteins in the blood will increase the pressure in the blood pressure.
