- 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.

Do teeth cause a chemical reaction to take place?
Teeth themselves do not cause a chemical reaction. However, when food comes into contact with teeth, the process of digestion begins with enzymes in saliva breaking down the food molecules into smaller components. This can be considered a chemical reaction in the context of digestion.
What type of chemical reaction take place in stomach during digestion?
In the stomach during digestion, hydrochloric acid is secreted to break down food and kill bacteria. This acid creates an acidic environment where enzymes can digest proteins. This process is a chemical reaction known as hydrolysis, where water is used to break down large molecules into smaller ones for absorption.

What is meant by thermodynamics of a chemical reaction?
It refers to the energy changes that take place during a chemical reaction.
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.
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.
Can a physical change always take place during a chemical reaction?
Yes
What take place during a chemical reaction?
During a chemical reaction, chemical bonds between atoms are broken and new bonds are formed, resulting in the rearrangement of atoms to create new substances. In a chemical reaction, the total amount of mass and energy remains constant due to the law of conservation of mass and energy. A chemical reaction can involve the release or absorption of energy in the form of heat, light, or electricity.
What type of reaction takes place during digestion of food?
breaking down of complex food material to simpler ones.
Where do chemical digestion take place?
In the duodenum
