- digestion of food starts in buccal cavity. saliva contain an enzyme "salivary amylase" or "phylin" which digest 30% carbohydrates into sugar.
- no digestion takes place in pharynx and oesophagus. food reaches into the stomach where gastric juice is secreted which consist of mucus, HCL and pepsin. pepsin break down protein into peptones.
- now the food enters into small intestine. here three juices are secreted - 1. bile juice - contains no enzyme for digestion but its bile salt play an important role in emulsification of fat. 2. pancreatic juice - it contains - pancreatic amylase - remaining carbohydrate gets digested into sugar , lipase - for digestion of fat into fatty acids and glycerol , trypsin - for digestion of peptones into amino acids. 3. intestinal juice - contains intestinal amylase for complete digestion of carbohydrates into glucose.
- the unabsorbed food is sent to large intestine where villi absorb water from the undigested food. the undigested food is then removed from the body via anus.

∙ 13y agoThere are many chemical reactions that compose digestion. These reactions depend on environment pH, food content, personal health and so on. The overall goal of these reactions is to break down complex food molecules (proteins, carbohydrates) into smaller, more manageable fragments that the blood can absorb Therefore, a generalized, overarching equation showing the intent of digestion is a decomposition reaction: AB --> A + B.

Human chemical reaction with male and female physical attraction?
Most of the chemical reaction in the human bodies take place internally during various processes like digestion, respiration, and ingestion. Naturally, unlike poles attract, this explains why males get attracted to the females.
Can a physical change always take place during a chemical reaction?
Yes
Where does most of the chemical digestion take place in humans?
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.
Could chemical digestion take place if mechanical digestion did not occur?
Mechanical digestion, i.e. your body breaking up the food into smaller pieces, is largely meant to speed chemical digestion up. We know that the rate at which the chemical reaction takes place is dependent on four things: the physical state of the reactants involved in the reaction, the temperature at which the reaction takes place, the concentration of the reactants, and the presence of a catalyst. Each influences the rate of reaction in different ways. Mechanical digestion breaks the food into smaller pieces, i.e. changes the physical state. With the larger pieces broken into smaller ones, more surface area is exposed. With greater surface area exposure, chemical digestion can take place much more rapidly. However, if for some reason you could get just huge chunks of food down your throat without chewing it, your stomach still churns (mechanical digestion) and the contractions in your intestines also help to break up food. So technically yes, chemical digestion would take place, but at a much slower and inefficient manner.
