Interlobular artery

Interlobular Artery

Diagram of the blood vessels of the kidney, with the Interlobular Artery labeled at center.

The Interlobular Artery is a branch of the arcuate artery of the kidney that extends into the renal cortex of the kidney. It is responsible for supplying blood to the renal cortex, including the glomeruli.

Structure

The interlobular arteries are located between the renal lobules. They arise from the arcuate arteries, which run along the border of the renal medulla and cortex. From there, they extend outwards towards the renal capsule.

Function

The primary function of the interlobular arteries is to supply oxygenated blood to the renal cortex. They do this by branching off into afferent arterioles, which lead to the glomeruli. Here, the blood is filtered, beginning the process of urine formation.

Clinical Significance

Damage or blockage to the interlobular arteries can lead to renal ischemia, or a lack of blood flow to the kidneys. This can result in kidney damage or failure, highlighting the importance of these arteries in maintaining renal health.
