mechanical digestion is essentially complete, but the other processes are ongoing or have not yet begun
The large intestine does not perform any digestion whatsoever. It is part of the gastrointestinal tract, but it only performs mainly absorption, as in water, some minerals, and some vitamins.
The mechanical process of digestion is first, followed closely by chemical digestion. After that it is mostly chemical digestion, then absorption, and lastly elimination, or defecation.
The alimentary canal which consists of the mouth, phraynx, esophagus, stomach, small intestine, and large intestine, and the accessory canal, which consists of teeth, the tongue, salivary glands, the liver, gall bladder, and pancreas.
The absorptive surface area of the small intestine is actually about 250 square meters (almost 2,700 square feet) – the size of a tennis court! How is this possible? The small intestine has three features which allow it to have such a huge absorptive surface area packed into a relatively small space:1. Mucosal folds: The inner surface of the small intestine is not flat, but thrown into circular folds. This not only increases the surface area, but helps regulate the flow of digested food through your intestine.2. Villi: The folds form numerous tiny projections which stick out into the open space inside your small intestine (or lumen), and are covered with cells that help absorb nutrients from the food that passes through.3. Microvilli: The cells on the villi are packed full of tiny hair like structures called microvilli. This helps increase the surface of each individual cell, meaning that each cell can absorb more nutrients.
Chewing is mechanical digestion.
The large intestine is mechanical digestion; it absorbs water and is involved in peristalsis. It has nothing to do with enzymes, which is chemical digestion.

chemical
The small intestine completes the process of chemical digestion.
Bile
small intestine
As far as I know there is no digestion at all in the large intestine, only absorption.
no it's biological, like washing powder
Yes, in part. Chemical digestion occurs in the mouth (saliva), stomach (gastric acid) and small intestine. The nutrients are mostly absorbed in the walls (lining) of the small intestine.
mouth,stomach and small intestine
Mechanical digestion is considered a physical process and includes actions such as mastication (chewing) and peristalsis (squeezing) of the intestine.
