Kidney: Lateral to Medial
capsule, cortex, medulla, renal papilla, renal calyces (minor/major), renal pelvis
renal a. → segmental a. → interlobar a. → arcuate a. → interlobular a. (cortical radiate/radial a.) → afferent arteriole → glomerular capillaries → efferent arteriole → peritubular capillaries/vasa recta → interlobular v. → arcuate v. → interlobar c. → segmental v. → renal v.
