So these are the two nutrients that are reabsorbed back by our body, and these are the two electrolytes that are reabsorbed by our body. Now, we haven't shown it in the diagram, but chloride ions are also reabsorbed by our body, so they move from the lumen into the cytoplasm. Now, finally, we have the movement of bicarbonate, just like this moves from the cytoplasm to the lumen. This also moves this way into our lumen. So these two ions are secreted. These two ions are absorbed, while glucose and amino acids are the two nutrient molecules that are also absorbed.
