Question

What is the percentage of total cardiac output that flows through the kidneys?

Answer 1

The kidneys receive approximately 20-25% of the total cardiac output. This significant blood flow is essential for their role in filtering blood, regulating fluid balance, electrolyte levels, and removing waste products from the body. In a typical resting adult, this equates to about 1 to 1.5 liters of blood per minute flowing through the kidneys.
