1. The Glomerulus Filters Water and Other Substances from the Bloodstream
Blood flow through the glomerulus as part of filtrationEach kidney contains over 1 million tiny structures called nephrons. Each nephron has a glomerulus, the site of blood filtration.

2. The Filtration Membrane Keeps Blood Cells and Large Proteins in the Bloodstream
Inside the glomerulus, blood pressure pushes fluid from capillaries into the glomerular capsule through a specialized layer of cells. This layer, the filtration membrane, allows water and small solutes to pass but blocks blood cells and large proteins.

3. Reabsorption Moves Nutrients and Water Back into the Bloodstream
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.

4. Waste Ions and Hydrogen Ions Secreted from the Blood Complete the Formation of
The filtrate absorbed in the glomerulus flows through the renal tubule, where nutrients and water are reabsorbed into capillaries. At the same time, waste ions and hydrogen ions pass from the capillaries into the renal tubule.

5. Urine Is 95% Water
The percentage composition of salts, ammonia, urea, water and other components of urine.The nephrons of the kidneys process blood and create urine through a process of filtration, reabsorption, and secretion. Urine is about 95% water and 5% waste products.
