The small intestine
The organ in the digestive system where the chemical breakdown of food primarily occurs is the stomach. Here, gastric acids and enzymes break down food into smaller particles for further digestion and absorption in the intestines.
It is the Duodenum!Actually, most chemical digestion, in humans, takes place in the small intestine.Chemical digestion takes place in the small intestine, the stomach and the mouth.
mouth
Chewing is a mechanic digestion as i found out here on WikiAnswers. So i hope i have answered you question those of you who have needed this little bit of information x.what the heck are u talking about?
Type your answer here... chemical to kinetic
The second stage of digestion occurs in the stomach. Here, food is mixed with stomach acid and digestive enzymes to further break down proteins and begin the process of nutrient absorption.
Potatoes are mostly starch, a type of carbohydrate. Your stomach only initiates the digestion of proteins and does not digest carbohyrates or fats. When carbohydrates are digested, it occurs in the duodenum, the first portion of the small intestines. Here they undergo both chemical and physical changes. The digestion of carbohydrates begin in the mouth with the secretion of salivary amylase. The physcial digestion is considered to be mechanical at this point and is produced by chewing (masticating) your potatoes.
When food is ingested in the mouth, it is propelled towards the stomach then to intestines and to the anus by peristaltic movement of the muscles. Without muscles, digestion will take couple of days to occur. Food is propelled slowly through small and big intestine as most of the absorption of food occurs here.
Digestion is a chemical process; burning is not a very correct word here but is frequently used.
