Final answer:
Arcuate arteries are not located at the base of the pyramids, but rather arch along the border between the renal cortex and medulla, making the statement false.
Step-by-step explanation:
The statement that arcuate arteries are located at the base of the pyramids is false. The arcuate arteries are indeed critical components in the kidney's blood supply, but they do not lie at the base of the renal pyramids. Instead, the arcuate arteries branch off from the interlobar arteries and arch along the border between the renal cortex and the renal medulla. This places them at the apex of the renal pyramids, not the base. They supply blood to the ascending limb of the loop of Henle that moves from the renal medulla to the renal cortex, as well as other structures in the cortex.
