Formation of Vortices (image) Saarland University Share Print E-Mail Caption Plasma influences the formation of vortices in blood. In one experiment, the researchers let blood plasma flow through a microfluidic channel such as is found in a constricted blood vessel. They observed vortices at the end of the channel, but also -- as shown in these images -- at the entrance to the channel. These vortices are created because of the viscoelastic properties of blood plasma. Credit Mathias Brust, Phys. Rev. Lett. 110, 2013, 078305.
