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 is digested by ptyalin.
Segmentation- series of stationary rhythmic contractions and relaxations of rings of intestinal smooth muscle; mixes intestinal contents. Segmentation mixes the cyme with intestinal secretions and brings it into repeated contact with the absorptive epithelium. The slow passage insures nutrient absorption.

Nothing is digested by the liver in the digestive system at all. So there is basically no answer to it.
It is starch! I think
Saliva
Starch (carbohydrates) is broken down (digested) to maltose by salivary amylase.
Yes, absorption of digested food occurs in chyme, primarily in the small intestine. Chyme, which is the semi-liquid mass of partially digested food and digestive juices, is mixed with bile and pancreatic enzymes in the small intestine, facilitating nutrient breakdown. The intestinal walls have villi and microvilli that increase the surface area for absorption, allowing nutrients like amino acids, sugars, and fatty acids to enter the bloodstream. However, the majority of nutrient absorption occurs after chyme has passed through the stomach.
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
The most important function of the intestinal villi is to increase the surface area of the intestinal lining, which enhances nutrient absorption. These small, finger-like projections contain numerous microvilli that further amplify the absorptive surface. This structure allows for efficient uptake of essential nutrients, electrolytes, and water from digested food into the bloodstream. Additionally, the villi play a role in the overall health of the intestinal lining, supporting digestion and immune function.
