Many of the small ions like sodium are quickly absorbed with active transport in a manner similar to the %Renal system @cite hall2011guyton.
An exception to this is calcium, which is carefully regulated by parathyroid hormone to ensure that the body's requirements are met @cite hall2011guyton.
Water is absorbed via the osmotic gradient that either naturally exists between the gut chyme and the blood or that is created by the active transport of substances across the intestinal wall @cite hall2011guyton.

As seen in Table 2, the macronutrient masses in the stomach are depleted based on different digestion rates and eventually reach zero.
The center column of plots shows the associated mass of substances in the gut chyme increase as the nutrients are removed from the stomach.
