What vessels serve the kidneys?

The kidneys are primarily supplied by the renal arteries, which branch directly from the abdominal aorta. Each renal artery enters the kidney at the hilum and further divides into smaller branches, supplying blood to the renal cortex and medulla. Venous drainage is provided by the renal veins, which drain into the inferior vena cava. This vascular system is essential for the kidneys' role in filtering blood and regulating various bodily functions.
