Conclusions Generalized Cavity Transport

Generalized transport in a hemocoel employs diffusion and convective dispersal within a confined space. Convective forces from the open circulation and the jerky movements of walking and flying disperse the particles perhaps adding components of superdiffusion.

Hemocoels avoid the higher energies and limits imposed by a closed circulation and pump to maintain high pressure to force fluid through peripheral resistances. Hemocoel transport is minia-turizable while pump-tube transport is not. Hemocoel transport should be useful in microfluidic devices.

We may also model hemocoel transport using mass action and percolation theory. We can simulate diffusion and dispersion on an incomplete lattice. We can explore the heterogeneities of surfaces bordering on the hemocoel cavity to determine what exogenous factors facilitate or impede mixing.

If diffusion distances are short and movements minimal, might we even imagine patterns of waves traveling through the volume? As movements increase, do contact of particles with walls and organs increase or decrease as the cohesive and adhesive forces change? How might the densities, concentrations and other intrinsic properties of particles influence the dynamics of hemocoels (Ref: Jacobs and Hendrickson, 1997)?
