The materials that are not absorbed and are egested are cellulose and lignin from plant matter, the remains of intestinal epithelial cells, bile pigments, and bacteria.

Fiber and other undigested materials (such as seeds) are not absorbed by the body.
The digestive bodies within cells that break down materials are called digestion. Digestion breaks down nutritional components within food and separates waste materials.
Not sure what you mean by '3 types of digestion', but there are three major food groups (carbohydrates, proteins, and fats), and each has a different method of digestion by the digestive system.
Ingestion, Propulsion, Mechanical digestion, Chemical Digestion, Absorption and Defecation
Once the food has reached the stomach and is worked on by enzymes to break them down into absorbable forms of proteins and carbohydrates and other nutrients the 'food' is now passed into the small intestine from where it is absorbed accross the small intestine lining through the cells into the blood and taken round the body. On its way round the body, the nutrients in the blood are absorbed into the places where they are needed. To sum this up, the body absorbs the nutrients into the blood through capillaries in the intestines.
It is part of the digestive system for the small and large intestines do their part in digesting all the food we eat. The small intestines takes the nutrients out of our food and puts it into our blood stream and the large intestines (colon) takes the moisture out of the digested food (bolus) for excretion.
Nutrients are absorbed in the intestines.
digestion
Dissolved Oxygen can diffused through the membrane in digestion system by concentration gradient however the amount absorbed should be minimal or negligible.
Absorbtion of proteins occurs in the small intestine. Digestion starts in the stomach.
The digestive system processes food into usable and unusable materials by chemical digestion. The usable materials are transported via the cells throughout the body while the unusable materials are sent to the large intestine where it waits to be disposed of.
It is digestion.The process used to break down food is called digestion. Digestion helps break down food so that the nutrients can be absorbed into the system.
The last part of the process is when your poo is egested through the anus.

Digestion is the breaking down of chemicals in the body, into a form that can be absorbed. It is also the process by which the body breaks down chemicals into smaller components that can be absorbed by the blood stream. There are also digestive system disorders. Read about them on the internet for more info.
The alimentary canal has glands which produces digestive juices which help in digestion from tract to system....it is then transported to liver.
The digestive bodies within cells that break down materials are called digestion. Digestion breaks down nutritional components within food and separates waste materials.
The materials that are not absorbed in the digestive system move through the large intestine, where water is reabsorbed. They are stored in the rectum in the form of feces, and are expelled through the anus.
