Figure 5.

ISF flux (positive values in the direction of arterial flow) averaged over one cycle as a function of BM position η in the arterial wall. Here, the BM is at r = r₀ + ηh such that η = 0 represents a BM immediately adjacent to the lumen and η = 1 represents a BM on the outer wall of the artery. Note that reverse flow is only achieved by ratios of $K_0/K_1<2.74\times 10^{-2}$. The fastest net reverse drainage shown here (for $K_0/K_1=2.68\times 10^{-2}$ and on the arterial lumen η = 0) is −2.64 × 10⁻⁵ μm³ s⁻¹.
