Do the kidneys have a higher blood flow than the heart liver and brain?

Yes, the kidneys do receive a higher blood flow relative to their size compared to the heart, liver, and brain. They receive about 20-25% of the cardiac output, which translates to around 1,200 milliliters of blood per minute in a healthy adult. This high blood flow is essential for their role in filtering blood and regulating body fluids and electrolytes. In contrast, other organs like the heart, liver, and brain receive a smaller proportion of blood flow relative to their size and metabolic needs.
