Renal arteries have what function?

Renal arteries have what function?

• A. They supply blood to the kidneys.
• B. They drain blood from the kidneys.
• C. They supply blood to the liver.
• D. They supply blood to the heart.

Answer: (A)

Renal arteries supply blood to the kidneys, delivering oxygen-rich blood from the abdominal aorta so the nephrons can carry out filtration and urine formation. They branch into smaller vessels to perfuse the entire kidney, ensuring the tissue receives the oxygen and nutrients it needs. This function is distinct from drainage by the renal veins and from the arteries that nourish other organs such as the liver or heart.
