This image from a 3D immersed-boundary lattice-Boltzmann simulation vividly depicts a suspension of deformable red blood cells travelling through a bifurcating blood vessel. The RBCs are immersed in a Newtonian plasma. The main branch of the blood vessel is 96-micrometer wide, and the child branches are 50-micrometer wide.
