The nurse is reviewing the blood supply to, within, and from the kidneys with a client. The blood supply is necessary so the kidneys can do the essential work of waste removal
Based on this information, what is the best response by the client to the nurse about the function of the afferent arterioles? A) Brings highly oxygenated blood to the kidneys
B) Supplies blood to the glomeruli
C) Carries blood away from the glomeruli
D) Empties blood into the inferior vena cava
B
Feedback:
The renal arteries diverge, forming smaller arteries, until they become the afferent arterioles that supply blood to the glomeruli. The kidneys receive their generous blood supply from renal arteries, which branch from the aorta close to the heart. Because it comes directly from the abdominal aorta, renal blood is highly oxygenated. Efferent arterioles arise from the glomeruli and carry blood away. The renal vein empties into the inferior vena cava.
