The small intestine is in the abdomen, connected to the stomach through the pylorus at the upper end, and connected to the large intestine at the lower end. Generally speaking, the small intestine is mainly used for the digestion of food, which is an important part of the small intestine. Therefore, people should have a better understanding of the small intestine and protect their own small intestine.

People need to eat every day, and where does the food we eat go? This is related to the small intestine. The small intestine is located in our abdominal cavity, with a total length of 46 meters, mainly divided into three parts: the duodenum, jejunum, and ileum. The digestion inside the small intestine is very important, and all the food we eat in a day must undergo chemical digestion by pancreatic juice, bile, and intestinal juice, as well as mechanical digestion by the movement of the small intestine. After the small intestine movement is completed, our food is also digested, and at the same time, nutrients are absorbed by the mucosa of the small intestine.

Even if a person does not have a small intestine, their physical health will also be affected, because without digesting food for a day, it will accumulate in our bodies, and over time, one’s health will be affected. The physiological function of the small intestine mainly manifests in the movement and secretion of the villi and the digestion and absorption, and it also has a close relationship with drug metabolism, such as the various forms of movement of the smooth muscle of the small intestine, which can complete the grinding, mixing, and stirring of food.

The intestine is an important part of digestion and absorption. Food enters the small intestine from the stomach, where digestion begins. Pancreatic juice, intestinal juice, and bile all have chemical digestion functions, plus the mechanical action of the small intestine movement, the digestion of food is basically completed in the small intestine. In daily life, people should also eat more easily digestible foods, which can also reduce the workload of the small intestine. It is also advisable to engage in appropriate exercise, especially after meals, which is also beneficial for the digestion of food.
