ALTERNATIVE VIEW ON BLOOD AND BLOOD PLASMA IN THE VASCULATURE

ALTERNATIVE VIEW ON BLOOD AND BLOOD PLASMA IN THE VASCULATURE Results of an experimental study of blood properties are reported. To approach the boundary conditions of blood biophysics in a real flow, the viscoelastic measurements are carried out on surfaces coated with a 10-nm thick fibrous layer composed of extracellular matrix protein. For native whole blood, a plateau of the shear elastic modulus as a function of frequency is observed. The immediate consequence of the shear elasticity is that it is necessary to exceed the stress threshold so that blood can flow. This elastic threshold depends on the boundary conditions. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Journal of Applied Mechanics and Technical Physics Springer Journals

Abstract

Results of an experimental study of blood properties are reported. To approach the boundary conditions of blood biophysics in a real flow, the viscoelastic measurements are carried out on surfaces coated with a 10-nm thick fibrous layer composed of extracellular matrix protein. For native whole blood, a plateau of the shear elastic modulus as a function of frequency is observed. The immediate consequence of the shear elasticity is that it is necessary to exceed the stress threshold so that blood can flow. This elastic threshold depends on the boundary conditions.
