1. How many kidneys do most people have?

  • Correct – Most people are born with two kidneys, but only need one. Here's why. Each kidney contains 1.5 million filters for blood called nephrons. Nephrons purify blood and remove waste products. Your body can survive on as few as 300,000 nephrons, but if the number of nephrons drops below 300,000 you may need dialysis treatment.

    That's why most people can live perfectly normal healthy lives with only one kidney, and why thousands of people each year donate one of their kidneys to tranplantation to save a life.

    Kidney donation is an altruistic and generous act.
