@muhammadrashidkhan61: How Your Kidneys Filter Your Blood Every day, your kidneys filter around 180 litres of fluid and give almost all of it back. Blood spreads through over a million tiny filters called nephrons. In each one, pressure squeezes water and small particles out of the blood, while cells and proteins stay inside. As that fluid winds through a long tube, your body reclaims the water, sugar and salts it still needs. What remains flows down as urine while clean blood leaves the other side. Filter. Reclaim. Remove. Without rest. Educational content only not medical advice.
