While the whole tract is used to digest food molecules the part that really takes in the rest is in the small intestine where it takes in the nutrients then goes to the large intestine that absorbs water from and eliminates the residues of digestion. Then the rest goes through the rectum.

In the Mouth then the second is the Stomach
Digestion in humans is completed in the small intestine. This is where nutrients from food are absorbed into the bloodstream for use by the body. The small intestine is lined with specialized cells that help break down food particles further and facilitate nutrient absorption.
Chemical digestion takes place in the stomach, the intestines, (saliva or enzymes) these parts of your body also use mechanical digestion.
The function of the alimentary canal, which includes the mouth and anus, in the human digestive system is to break down food into smaller molecules that can be absorbed by the body for energy and nutrients. This process involves the mechanical and chemical digestion of food as it travels through the digestive tract.
Mechanical digestion is produced by breaking down and chewing food. This process involves the physical breakdown of food into smaller pieces that can be further digested and absorbed by the body.
the small intestine
Maximum digestion takes place in duodenum .
It turns to Bile and is excreted out of your rectum.
It ends at the small intestine. From the small intestines, the digested food enters the bloodstream through the intestinal walls, while the undigested food goes into the large intestine and comes out of our body as faeces.
For food to properly pass through the alimentary canal, digestion must first occur. The process of moving food through the alimentary canal is called propulsion.
Food is pushed along the alimentary canal by peristalsis, alternating waves of contraction and relaxation in the smooth muscles lining the canal.
Digestion is completed and absorbed into the bloodstream

Folds and projections of alimentery canal increase surface area for digestion and absorption of food.
In the Mouth then the second is the Stomach
Digestion includes the mixing of food, its movement through the digestive tract, and chemical breakdown of the larger pieces of food into smaller pieces. Digestion begins in the mouth, when we chew and swallow, and is completed in the SMALL INTESTINE.
The final process of digestion is accomplished in the small intestine. In subsequent portions of the digestive tract, water is reabsorbed from undigested food waste.
