fiber
No, undigested food is not part of body cells. Undigested food consists of components that the body was unable to break down and absorb during the digestion process. The body processes undigested food differently, such as excreting it through feces.
large intestine
Peristalsis also occurs in the stomach so that it can mix the food together with stomach juices and move the partially digested food into the first part of the small intestine (known as the duodenum).
Large intestines.
the part of the alimentary canal responsible for peristalsis is the oesophagus or the food pipe.by wave like movements of the smooth muscles on the wall of the food pipe the food is sent to the stomach.
When we swallow, food is moved down into the stomach from the mouth. This is peristalsis, and it's a rhythmic contraction of smooth muscles. A link can be found below for more information.
the correct answer to this question is not your stomach, but it is your gall bladder
By the large and small intestine. The feces are formed in the large intestine, these are undigested foods.
The large intestine and rectum are responsible for excreting undigested food in the form of feces. These organs absorb water and nutrients from the food, leaving behind waste products that are then expelled from the body.
Fiber is an important part of a diet because it stimulates peristalsis. Food is moved through the alimentary canal by the muscular contraction called peristalsis, and if such movement becomes sluggish, it is bad for your digestion and health.
The large intestine is part of the digestive system. Its main function is reabsorption of water from undigested food waste.
The two types of movement in the small intestine are peristalsis and segmental movements. Segmental movements, which are more common in the small intestine than peristalsis, move the digesting food back and forth in a part of the small intestine. This lets the food mix with intestinal juices. Peristalsis is one-way movement that pushes the digesting food through the small intestine toward the large intestine.
