Interlobar arteries

Interlobar arteries are a part of the renal circulation. They are responsible for supplying blood to the renal cortex and renal medulla. The term "interlobar" is derived from the Latin words "inter" meaning between and "lobar" meaning lobes, referring to the location of these arteries between the lobes of the kidney.

Etymology

The term "interlobar arteries" is derived from the Latin words "inter" meaning between and "lobar" meaning lobes. This refers to the location of these arteries between the lobes of the kidney.

Anatomy

The renal artery branches off the abdominal aorta and enters the kidney at the hilum. Within the kidney, the renal artery branches into segmental arteries, which further divide into interlobar arteries. These arteries run between the renal pyramids, hence the name "interlobar". The interlobar arteries then branch into arcuate arteries, which in turn give rise to interlobular arteries.

Function

The primary function of the interlobar arteries is to supply blood to the renal cortex and renal medulla. They carry oxygenated blood from the heart to the kidneys for filtration. The filtered blood is then returned to the circulation via the renal vein.

Clinical significance

Abnormalities in the interlobar arteries can lead to various renal disorders. For instance, narrowing of these arteries due to atherosclerosis can result in renal artery stenosis, which can cause high blood pressure and kidney damage. Similarly, blockage of these arteries due to a blood clot can lead to renal infarction, which can cause acute kidney injury.
