Alongside the renal pyramids
What kind of blood flow is demonstrated in the interlobar artery?
Low resistance
What is the Bbundary between the cortex and medulla?
Arcuate artery
Arcuate artery
Branch of the interlobar artery located at the base of the medulla
What do arcuate arteries give rise to?
Interlobular arteries
What kind of blood flow is demonstrated in the arcuate arteries
Low resistance
Interlobular artery
