MICROANATOMY

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: -Glomerular filtration is the first step in making urine. It is the process that your kidneys use to filter excess fluid and waste products out of the blood into the urine collecting tubules of the kidney, so they may be eliminated from your body.

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.

Detailed explanation-4: -The glomerulus filters water and small solutes out of the bloodstream. The resulting filtrate contains waste, but also other substances the body needs: essential ions, glucose, amino acids, and smaller proteins. When the filtrate exits the glomerulus, it flows into a duct in the nephron called the renal tubule.
