Absorption in the Small Intestine: General Mechanisms. Virtually all nutrients from the diet are absorbed into blood across the mucosa of the small intestine. In addition, the intestine absorbs water and electrolytes, thus playing a critical role in maintenance of body water and acid-base balance.
Water is mainly absorbed in the small intestine, along with any minerals it contains. The small intestine is well-suited for this task, as its lining is covered with small, finger-like protrusions called villi that increase surface area and improve the absorption of nutrients.
