Detailed explanation-1: -The nephrons work through a two-step process: the glomerulus filters your blood, and the tubule returns needed substances to your blood and removes wastes. Each nephron has a glomerulus to filter your blood and a tubule that returns needed substances to your blood and pulls out additional wastes.
Detailed explanation-2: -A glomerular filtration rate (GFR) is a blood test that checks how well your kidneys are working. Your kidneys have tiny filters called glomeruli. These filters help remove waste and excess fluid from the blood. A GFR test estimates how much blood passes through these filters each minute.
Detailed explanation-3: -Water Filtration and Reabsorption in the Nephron In the glomerulus, water is initially filtered out, along with the other solutes e.g. Na+, K+ and glucose. From here H2O needs to be reabsorbed into the tubule cells and then back into the interstitial space.
