urine - (Mar/29/2006 )
which mechanism used to form urine requieres a high blood pressure?
and my answer is: glomerular filtration.
am i correct?
Sounds sensible to me
I would think a fair amount of pressure would be needed for the loop of henle also.
The mechanisms of action of the loop of henle (countercurrent multiplier) is based primarily on an extremely high sodium content in the renal medulla. This is achieved by the active reuptake of sodium. This in turn cause a huge loss of water from the nephron. No real need for high pressure, it's mainly down to a chemical gradient. In the Bowman's capsule the only mechanism for filtration is dependent on the renal blood pressure as there are no active transporter mechanisms.
