All blood in the body flows through the kidneys hundreds of times each day The kidneys push the liquid part of blood through tiny filters called nephrons then reabsorb most of the fluid back into the blood The fluid and waste products that the kidneys dont reabsorb are excreted as urine The rate of blood flow through the kidneys is the glomerular filtration rate or GFR The glomeruli are microscopic bundles of blood vessels inside nephrons and are crucial parts of the filtering system The glomerular filtration rate cant be measured directly thats where measuring creatinine and creatinine clearance comes in Blood entering the glomerulus has filterable and nonfilterable components Filterable blood components include water nitrogenous waste and nutrients that will be transferred into the glomerulus to form the glomerular filtrate How glomerular filtration works The first step in making urine is to separate the liquid part of your blood plasma which contains all the dissolved solutes from your blood See Answer
