Résumé

The dynamic distribution of red blood cells (RBCs) plays a crucial role in cerebral oxygenation, metabolism and many brain disorders (e.g. Alzheimer, ischemic stroke). Despite the growing number of studies on blood rheology in microcirculation, there remains still a big need for detailed experimental data on RBCs distribution in network of microchannels. To our best knowledge, this is the first experimental study of blood cell dynamics in simple networks of microchannels (height less than 10µm) under well controlled conditions which allows a systematic understanding of effects caused by single blood cells.
