TED-Ed: How do your kidneys work? - Emma Bryce

The video explains the vital functions of kidneys, including filtering blood, removing waste, and regulating water levels. Kidneys use nephrons to filter blood, reabsorb necessary nutrients, and excrete waste as urine. They also regulate body fluid levels and secrete hormones like renin and erythropoietin. Without kidneys, waste would accumulate, leading to system overload.
