And this allows the reabsorption the movement of calcium from the lumen into the cell and eventually into our interstituency. So we see that the three things that are reabsorbed inside the distal convolute tubule is calcium, it's chloride and its sodium. Now, on the basil lateral side of the membrane, we also have our sodium calcium cotransporter protein. And this allows the movement of calcium from within the cell to our interstitium. And what this does is it allows our distal convoluted tubular to reabsorb our calcium into the surrounding tissue and eventually into the peritubular cavities, our blood system. Now, you should note that a type of hormone known as the parathyroid hormone stimulates the reabsorption of calcium within our distal convoluted tubule.
