Water follows urea as it is reabsorbed from the collecting duct. This actually increases the concentration of urea in the tubular fluid despite some of it being reabsorbed. This means that urea concentration only drops moderately when the urine concentration falls due to increased reabsorption of water.

The regulation of how much calcium is reabsorbed occurs in the ascending limb of the loop of henle, the distal tubule and collecting ducts. [[Calcium Homeostasis - Anatomy & Physiology #Parathyroid Hormone (PTH)| Parathyroid hormone]] stimulates reabsorption. It is normal for a 1-2% excretion of calcium to occur
