摘要
Cardiovascular 網絡s span the body by branching across many generations of vessels. The resulting structure delivers blood over long distances to supply all cells with oxygen via the relatively short-range process of 擴散 at the capillary level. The structural features of the 網絡 that accomplish this density and ubiquity of capillaries are often called space-filling. There are multiple strategies to fill a space, but some strategies do not lead to 生物ly adaptive structures by requiring too much construction material or space, delivering resources too slowly, or using too much power to move blood through the system. We empirically measure the structure of real 網絡s (18 humans and 1 mouse) and compare these observations with predictions of model 網絡s that are space-filling and constrained by a few g
