Description
Aquatic sponge tissue is the quintessential living, porous, viscoelastic solid. These animals grow in a myriad of forms, intuitively to maximize flow through their unidirectional water and particulate transport system, or aquiferous system, however the data remain equivocal. Several studies have quantified the dissipative loss from hydraulic transport while ignoring friction from particle-tissue and particle-water interactions. Here, the conceptual power behind the unique physiology of a sponge is used as leverage. Since dissolved particle transport through their bodies is unidirectional, the operation of a living sponge is a prescient example of a coupled irreversible transport process. Onsager transport equations are presented, and meta-analyses reveal estimates of transport coefficients within a rigorous non-equilibrium thermodynamic framework. Sponge tissue is idealized as a complex network of parallel membranes following recent progress in Peusner network thermodynamics, and preliminary lattice Boltzmann simulations are presented.
