Abstract

Red blood cells (RBCs) squeeze through narrow capillaries as they transport oxygen to tissues and carbon dioxide to the lungs. The deformability of RBCs has been shown to depend on the viscoelasticity of the cell membrane and cytoplasm as well as the surface area to volume ratio (SA:V ratio) of the cell. In certain pathological diseases such as malaria, RBCs undergo restructuring of the membrane structure and modifications to the cell shape, which significantly reduce their deformability. Nonetheless, it is still unclear which factor has the greatest impact on the passage of RBCs through small capillaries. Here, we present a systematic analysis designed to identify the individual contributio..
