Chemical digestion occurs in the mouth and (mainly) in the stomach. The small intestine is where a majority of absorption occurs, the large intestine mainly absorbs water.
Actually only protein is digested in the stomach the majority of the rest is digested in the small intestine. Some starch is digested by salivary amylase in the mouth the rest is digested by pancreatic amylase in the duodenum/jejynum. The protein is digested entirely in the stomach as this is the only area with a pH low enough for the action of pepsin. Fats are digests using secretions of the gall bladder in the dudodenum/jejunum.

∙ 13y agoThat depends on what you mean by the first organ used. Technically, the salivary glands are the first organs that contribute to the process of digestion. specifically, the parotid glands are the ones that produce and secrete an enzyme called salivary amylase that begins the process of digesting carbohydrates.
If, instead, you are asking which is the first organ in which chemical digestion takes place, then that would be the oral cavity. That is where chemical digestion with salivary amylase takes occurs.
Just for further clarification, the stomach is not the main organ of digestion. That is a commonly held myth. It is really the small intestine, in the first section called the duodenum, that digests all three types of foods; carbohydrates, proteins, and fats. The stomach, contrary to popular belief, is only a minor player in the whole scheme of things that involve digestion because it only partially digests one type of food; proteins.

The primary organ responsible for absorption of products of digestion?
The primary organ of digestion and absorption of nutrients is the small intestine, especially the duodenum.In general, you could say the stomach breaks down the food, the small intestine digests and absorbs the food, and the large intestine absorbs water.
What are the six functional activities of the digestive system?
Ingestion, Propulsion, Mechanical digestion, Chemical Digestion, Absorption and Defecation
What type of digestion is produced by breaking down and chewing food?
Chemical digestion
Main function of small intestines?
chemical digestion and absorption of nutrients
Contrast mechanical digestion with chemical digestion and give an example of each?
Physical digestion is, basically, "mashing." The food is ground up (by the teeth), mashed into a paste (by the stomach), and so forth. It's mixed with other foods in the process, but no new molecules are produced. Chemical digestion involves chemical reactions, and new molecules ARE produced. The action of enzymes in saliva, gastric juices, and so forth is a form of chemical digestion.
Organ responsible for chemical digestion and absorbtion of food?
The major organ responsible for chemical digestion and absorption of food is the small intestine.
Which breakdown of large molecules of food for absorption?
I think chemical digestion
What organ in the mouth begins the chemical digestion of food?
Salivary glands
What are the organs of the digestion in order that the food passes through?
The mechanical process of digestion is first, followed closely by chemical digestion. After that it is mostly chemical digestion, then absorption, and lastly elimination, or defecation.
What is the energy used for digestion and absorption of food eaten reffered to as?
I don't know if this helps, but the energy that you get out of food is chemical energy.
The breakdown of large food molecules into their basic building blocks by enzymes is called?
phagocytosis
What 2 things happen in the small intestine?
Chemical digestion and absorption of nutrients occurs in the small intestine.
What is the name of the organ in the digestive system where the chemical breakdown of food primarily occurs?
Some chemical digestion of carbohydrates occurs in the mouth with salivary amylase. Most chemical digestion occurs in the duodenum of the small intestine.
Process by which the body takes in and uses food?
The human body breaks down food for absorption and assimilation through the process of digestion. Both mechanical and chemical digestion is used to spread the food pieces through the human body.
The primary organ responsible for absorption of products of digestion?
The primary organ of digestion and absorption of nutrients is the small intestine, especially the duodenum.In general, you could say the stomach breaks down the food, the small intestine digests and absorbs the food, and the large intestine absorbs water.
What role does digestion and absorption play in homeostasis?
to absorb food
What is the major site of food digestion and absorption?
The small intestine.
