The table below shows the concentrations of large proteins (such as albumin) and glucose in the blood plasma, glomerular filtrate, and urine of a healthy individual:
| Substance | Concentration in Blood Plasma / g dm−3\text{g dm}^{-3}g dm−3 | Concentration in Glomerular Filtrate / g dm−3\text{g dm}^{-3}g dm−3 | Concentration in Urine / g dm−3\text{g dm}^{-3}g dm−3 |
|---|---|---|---|
| Large Proteins | 70.0 | 0.0 | 0.0 |
| Glucose | 1.0 | 1.0 | 0.0 |
Using your knowledge of the structure and function of the nephron, explain the physiological processes that account for these concentration values.
