Glucose is filtered in the nephron through a specific process that occurs within the kidney's filtration system.
Here's how it works, based on the provided reference:
When blood flows through the glomeruli in the kidneys, glucose, along with other small molecules, is freely filtered from the blood into the tubular fluid within the nephron. This initial filtration process allows glucose to enter the nephron's tubules. Importantly, in a healthy individual, almost all of this filtered glucose is subsequently reabsorbed back into the bloodstream. This reabsorption primarily takes place in the proximal tubule of the nephron.
| Process | Location | Description |
|---|---|---|
| Filtration | Glomeruli | Glucose is filtered from the blood into the tubular fluid. |
| Reabsorption | Proximal Tubule | Nearly all filtered glucose is reabsorbed back into the bloodstream. |
