Final answer:
The renal arteries are responsible for delivering 25% of the total cardiac output to the kidneys, which they enter and branch further to supply the nephrons with blood.
Step-by-step explanation:
The arteries that debvery minute to the kidneys are the renal arteries. The renal arteries branch out from the aorta and enter the kidneys. Inside the kidneys, they subdivide into several segmental arteries, which further divide into interlobar arteries and then into arcuate arteries. The arcuate arteries split into cortical radiate arteries, which finally branch into many afferent arterioles that supply the nephrons.
While the renal arteries are responsible for bringing blood into the kidneys, the renal veins trace the path of these arteries in reverse to carry filtered blood away from the kidneys and eventually merge with the inferior vena cava. Therefore, the correct answer to the question is (a) Renal arteries.
