“…238−242 In particular, a recent study introduced the concept of intermediate shear rate, where the effect of RBC aggregation on blood viscosity diminishes and the deformation of RBCs becomes the dominant factor affecting viscosity. 243 This phenomenological approach offers a more comprehensive understanding of blood's shear-dependent behaviors, bridging the knowledge gap between aggregation and deformability behaviors of RBCs.…”

“…A comparison between Newtonian and non-Newtonian models for intracranial atherosclerotic stenosis cases showed that non-Newtonian models are more accurate for simulating wall shear stress . As new models adeptly capture blood’s shear-thinning behavior and yield stress, there has been an increasing understanding of the interactions and effects of red blood cells (RBCs) and platelets on blood rheology. − In particular, a recent study introduced the concept of intermediate shear rate, where the effect of RBC aggregation on blood viscosity diminishes and the deformation of RBCs becomes the dominant factor affecting viscosity .

The investigation of biological fluidic mechanisms is a persistent topic of interest and offers valuable inspiration to address the challenges confronting chemical engineering, particularly with respect to the obligations of sustainability. Accordingly, given the advancements of multidisciplinary integration and digital transformation, the methodologies in chemical engineering represent potent instruments for characterizing the flow and transport features of biological vascular systems. In this Review, a qualitative explication of common tubular structures and their corresponding biofluid patterns in both vascular plants and humans is provided, grounded in a physiological perspective. Theoretical and numerical models, such as computational fluid dynamics (CFD), in engineering are introduced as effective and efficient prediction and analysis tools for quantitatively characterizing biofluid transport mechanisms, including fluid−structure interactions. Furthermore, typical pathologies resulting from multiphase biofluid dysfunction in vascular organisms are analyzed with physiological and chemical engineering methodologies. The integrated perspective provides an opportunity to extend the fundamental understanding of biological processes and in turn promotes the nature-inspired transformative advancements in the field of chemical engineering.
