The table below shows the concentrations of various substances in three different fluid compartments of a healthy human nephron: blood plasma in the afferent arteriole, glomerular filtrate in the Bowman's capsule, and the final urine.
| Row | Substance | Concentration in Blood Plasma (g dm−3g\ \text{dm}^{-3}g dm−3) | Concentration in Glomerular Filtrate (g dm−3g\ \text{dm}^{-3}g dm−3) | Concentration in Urine (g dm−3g\ \text{dm}^{-3}g dm−3) |
|---|---|---|---|---|
| A | Large proteins | 70.0 | 70.0 | 0.0 |
| B | Urea | 0.3 | 0.0 | 20.0 |
| C | Glucose | 1.0 | 1.0 | 0.0 |
| D | Sodium ions | 3.2 | 0.0 | 3.2 |
