Biological tissues with low porosity
WebQuestion: Biological tissues are deformable. Therefore, the porosity ? depends on the volume dilation, e = (Vf-Vo)/Vo. Assuming that the total volume of cells and extracellular matrix molecules do not change during tissue deformation and that the initial porosity is ?0, derive the relationship between ? and e.
