Models of the medullary microcirculation

Renal medullary microcirculation

“…Their model was later extended by McNeely (62) to account for the fact that vasa recta terminate at various depths in the medulla. Conservation equations were modified to incorporate all vessels, and cortico-medullary gradients of urea and NaCl were assumed to increase exponentially in the inner medulla, consistent with the findings of Koepsell et al (63).…”
