Nothing is digested by the liver in the digestive system at all. So there is basically no answer to it.
The ileum is the end of the small intestine it basically absorbs digested material through its wall which enters into the bloodstream.
Starch is digested by ptyalin.
The ileum is long in order to facilitate absorption of nutrients from digested food. Its length provides a large surface area for nutrient absorption to occur efficiently. This is important for the body to extract as many nutrients as possible from the food we consume.
The ileum is a part of the digestive system. It is the final section of the small intestine where absorption of nutrients from digested food occurs before it passes to the large intestine.
Protien
It is starch! I think
Saliva
The nutrient that is not digested but stimulates intestinal muscle contractions is fiber. Fiber is a type of carbohydrate that may be soluble or insoluble.
Starch (carbohydrates) is broken down (digested) to maltose by salivary amylase.
Most nutrient reabsorption occurs in the small intestine, particularly in the jejunum and ileum. These sections of the small intestine have specialized cells that absorb nutrients such as sugars, amino acids, and vitamins from digested food into the bloodstream for distribution to the rest of the body.
the portion of the mammalian small intestine that follows the duodenum and precedes the ileum that is the function of absorbing digested food
CelluloseAnswer:To be a nutrient a food material has to be digested and incorporated into the body as stored fat, converted to muscle or other protein, or converted to energy. So no nutrient as "not digested"/ Non-nutrient materials which provide other functions are fiber and water, and minerals asn trace chemicals such as salt, iron, zinc. Vitsmins can be regarded as supplimental to the body's own production. fibre can not be digested
