Topic: A Story of Two Circulations: Blood Flow and Transport in the Human Placenta

The human placenta is a unique multi-functional organ. It is a life-support system that not only nourishes a growing fetus, but also determines his or her life-long health. The placental primary exchange units, terminal villi, host complex networks of fetal capillaries and are interfaced with maternal blood, percolating a disordered porous medium. While placental transport at the micro-scale can be described by established models, systematically upscaling the transport and quantifying the associated uncertainty at the organ-level remain open challenges [1]. This talk will summarise recent progress in advanced 3D microscopy and its assimilation into mathematical models that predict placental function [2]. The models reveal a surprising role of microstructure in the upscaled predictions and demonstrate certain universality of reduced-order approximations for a wide class of solutes [3]. The developed approaches could also be useful for quantifying solute exchange in other complex microvascular systems.
