Water does not need to be digested in order to be used by the body. Therefore, it is simply absorbed from the digestive system into the circulatory system through the walls of the gut.
The water in your food helps to give a liquid property to chyme, which is a mixture made in the stomach after it churns the food and it is physically broken down into smaller pieces. Here water is important because since it is a solvent for both food and the enzymes needed to digest it. Therefore,you could say it is responsible for bringing the enzyme and substrate together.
It is first absorbed through the small intestine with salt dissolved in it. Then it travels through the gut as the other food is digested. When all the food that can be digested is digested and absorbed, the material left behind is the feces. This is in the large intestine. This is the final part of the digestive system where water is absorbed. All the excess water is absorbed here during the time the feces stays in the large intestine. The reason why stooles in diarrhea is watery is because the bowel movement is quite fast. This reduces the retention time of feces in the intestine so there is not enough time to absorb water.
The water in the digestive system comes from the food you eat, the drinks and the digestive juices produced in the gut.
