The segmental arteries of the kidney are the first branches of the renal artery.

Explanation

The renal artery is a major blood vessel that branches off from the abdominal aorta and supplies blood directly to the kidneys. Upon entering the kidney, the renal artery divides into smaller arteries, including the segmental arteries. These segmental arteries then supply different regions of the kidney, ensuring that the various parts of the kidney receive adequate blood flow for filtration and other functions. Understanding the branching system of arteries in the renal system is crucial for comprehending how blood supply is maintained in the kidneys, which play a vital role in regulating bodily fluids, electrolyte balance, and waste elimination.
