Artery - Arcuate

: They arise from interlobar arteries at right angles and arch over the bases of the renal pyramids.

: The arcuate arteries give rise to cortical radiate (interlobular) arteries, which radiate out into the cortex toward the kidney's surface.

These are vital components of the renal circulatory system, facilitating blood filtration and urine production.

: These vessels do not anastomose (connect) with each other, making the central part of the renal lobe particularly susceptible to ischemic injury if blood flow is compromised. 2. Arcuate Artery of the Foot

: They are situated at the corticomedullary junction, which is the border between the renal cortex (outer layer) and the renal medulla (inner layer).
