The small intestine of the digestive tract is the predominant location for water and mineral absorption.

The major organ of the mineral and water absorption is small intestine basically and the exact location is hind gut. The hind gut is the end portion of the alimentary canal of the vertebrates which has major function in water absorption along with the storage and elimination of the residual food.

The small intestine absorbs most of the water which mainly occurs by osmosis. Water gets absorbed by diffusion down the osmotic gradient and is absorbed into the intracellular space. Also, the nutrients of the diet get absorbed in the blood across the mucosal layer.

This important procedure occurs in the gut and makes the absorption possible by the formation of an electrochemical gradient of the sodium across the epithelial boundary of lumen. The villi and folds increase the surface area for absorption
