How much of our body's entire blood supply passes through the kidneys each minute? 45-55\% 70-75\% 5-10\% \( 20-25 \% \)

Surprise! It's actually around 20-25% of our entire blood supply that passes through the kidneys each minute. That’s quite a workload for these bean-shaped organs! They continuously filter our blood, removing waste products while helping to regulate blood pressure, electrolyte balance, and water levels. It’s like having tiny factories that work around the clock to keep our bodies clean and healthy. To visualize just how vital the kidneys are, think of them as the body’s very own natural filtration system. Each day, they filter about 50 gallons of blood, extracting about 1.5 quarts of waste in the form of urine. Next time you think about those little beans, remember they are tirelessly cleaning up behind the scenes to keep your body's systems in tip-top shape!
