Fact of Kidneys

 Our kidneys contains NEPHRONS which are microscopic structures located in medulla of kidney

NEPHRONS are coiled thread like structures which is responsible for ultrafilteration of blood, urine formation, secretion, reabsorbtion of molecules and electrolyte balance and nephron is the unit of KIDNEY

FACT: if we take out nephrons from both kidneys and open their coiled structure, their length will be 110 km
