What are the tiny intrarenal branches that arise from the interlobar arteries called?

The tiny intrarenal branches that arise from the interlobar arteries are known as arcuate arteries. These arteries are essential as they curve along the boundary between the renal cortex and the renal medulla, forming an important part of the vascular architecture within the kidney. They supply blood to the renal cortex, facilitating the delivery of oxygen and nutrients to the nephron structures, including the cortical nephrons that are primarily responsible for filtration.

Arcuate arteries serve as a crucial link within the renal blood supply, allowing for effective regulation of blood flow and contributing to the overall functioning of the kidney in processes such as filtration, reabsorption, and secretion. Understanding this vascular configuration is vital for comprehending kidney physiology and the implications of vascular diseases in renal health.
