In a tissue type that experiences significant mechanical stress, such as the intestinal lining, you would expect to see an abundance of tight junctions and desmosomes between the individual cells. Tight junctions help maintain the integrity of the epithelial barrier, preventing leakage of substances, while desmosomes provide strong adhesion between cells, allowing them to withstand tensile forces. This structural organization is crucial for maintaining the tissue's function and integrity under stress.
mechanical digestion is essentially complete, but the other processes are ongoing or have not yet begun
The large intestine primarily absorbs water and electrolytes from undigested food, with little to no involvement in chemical or mechanical digestion. Its main role is to form and store feces before they are eliminated from the body.
Food passes through the following organs in order during the process of digestion: mouth, esophagus, stomach, small intestine, large intestine, rectum, and anus. Each organ plays a specific role in breaking down the food into nutrients that can be absorbed by the body.
In an individual, processes that could occur include digestion of food in the stomach, absorption of nutrients in the small intestine, and filtration of waste products in the kidneys.
The large intestine typically weighs around 1.5 kilograms (3.3 pounds) in a healthy adult. Its weight can vary depending on factors such as the individual's size, diet, and overall health. The large intestine's primary function is to absorb water and electrolytes, as well as to store and eliminate waste.
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
As far as I know there is no digestion at all in the large intestine, only absorption.
small intestine
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.
