In chemical digestion are foods physically broken down into smaller pieces by chewing?
Chemical digestion is the process of enzymes and acids breaking the bonds that make up the food. Proteins are broken down into their chemical components by enzymes. Chewing is the mechanical process, aka as mastication, which cuts and grinds the food into smaller particles that are mixed with saliva to form a ball-shaped mass or bolus. The saliva contains an enzyme analaise, which starts the first stage of chemical digestion. This enzyme breaks the long carbon chemical chains that make up starches into simpler compounds called sugars.
The "slimy" bolus then travels down the esophagus through the pyloric valve into the stomach. Here, the strong muscular stomach, together with the hydrochloric acid churns the chyme, mixing it with the acid and the bolus is further reduced in size and chemical complexity. The resulting food-stuff is now called chyme.

What two digestive system occurs in the mouth?
Mechanical and chemical digestion both occur in the mouth (physically chewing and when saliva breaks down food into smaller bits).
What process increases the surface area of foods prior to chemical digestion?
Mechanical digestion is the process that increases the surface area of foods prior to chemical digestion. This process involves chewing, churning in the stomach, and segmentation in the small intestine to physically break down food into smaller pieces, allowing enzymes to work more efficiently.
What type of digestion is produced by breaking down and chewing food?
Mechanical digestion is produced by breaking down and chewing food. This process involves the physical breakdown of food into smaller pieces that can be further digested and absorbed by the body.
Which of the following digestive processes is NOT considered a chemical change?
Mechanical digestion is not considered a chemical change. Mechanical digestion involves physically breaking down food into smaller pieces through chewing and mixing with digestive juices, whereas chemical digestion involves enzymes breaking down macromolecules into smaller molecules.
The digestive system undergoes two kinds of digestion?
The two kinds of digestion in the digestive system are mechanical digestion, which involves physically breaking down food into smaller pieces through chewing and grinding, and chemical digestion, which involves the breakdown of food molecules into nutrients by enzymes and acid in the digestive tract.
What are two phases of the digestive process?
The two main phases of the digestive process are the mechanical digestion phase, which involves physically breaking down food through chewing and the movement of the stomach and intestines; and the chemical digestion phase, where enzymes and stomach acids break down food into smaller molecules that can be absorbed by the body.
How is mechanical digestion is different than chemical digestion?
Chemical digestion uses enzymes and other chemicals to break the bonds in food. Mechanical digestion is basically the teeth grinding the food into physically smaller pieces.
Is your tongue involved in mechanical or chemical digestion?
The tongue is involved in both mechanical and chemical digestion. It helps break down food into smaller pieces through chewing (mechanical digestion) and it also helps mix food with saliva, which contains enzymes that start breaking down carbohydrates (chemical digestion).
Is digestion of food physical change or chemical change?
Digestion of food is a combination of physical and chemical changes. Physical changes occur as food is broken down into smaller pieces through chewing and grinding. Chemical changes take place as enzymes in the digestive system break down food into simpler molecules that can be absorbed by the body.
Type of digestion that involves using enzymes and other body acid to break food down into smaller molecules?
Mechanical digestion is the physical mashing and pulling apart of food like chewing your food. Chemical digestion uses acids and enzymes to chemically break down the food until it is small enough to be absorbed through the wall of the small intestine.
What is the first part of mechanical digestion called?
The first part of mechanical digestion is chewing, also known as mastication. This process involves breaking down food into smaller pieces in the mouth, which increases the surface area for enzymes to further break down the food during chemical digestion.
What does chemical digestion in the stomach require?
The process of chemical digestion starts is your mouth! When you start chewing, your saliva helps break down the food as it goes down the esophagus.
