What percentage of cardiac output do the right and left renal arteries supply to the kidneys?

The kidneys receive a substantial portion of the body's cardiac output to perform their essential functions, such as filtration and regulation of blood composition. The correct percentage of cardiac output supplied to the kidneys by the right and left renal arteries is approximately 20%. This significant blood flow is critical because the kidneys require a rich supply of oxygen and nutrients to carry out their filtering processes effectively. Understanding this proportion is vital for comprehending renal physiology and how the kidneys maintain homeostasis within the body.
