Verified step by step guidance

Begin by understanding the anatomy of the kidney and its blood supply. The kidneys receive blood through the renal arteries, which branch directly from the abdominal aorta.

Recognize that the renal arteries are responsible for delivering a significant portion of the cardiac output to the kidneys. This is crucial for the kidneys to perform their function of filtering blood and producing urine.

Consider the role of the renal arteries in the context of cardiac output. Cardiac output is the volume of blood the heart pumps per minute, and the kidneys receive about one-fourth of this output under normal resting conditions.

Identify the correct anatomical term that matches the description given in the problem. The renal arteries are the primary vessels delivering blood to the kidneys, not the segmental, interlobar, or cortical radiate arteries.

Conclude that the renal arteries are the correct answer, as they are the main arteries delivering approximately 1200 ml of blood to the kidneys each minute under normal resting conditions.
