What are two examples of physical and chemical changes in the digestive system?

Muscular movement in the stomach causes food particles to become even smaller. This is a physical change. Enzymes and digestive juices in the stomach work to chemically break down proteins into amino acids. This is a chemical change.

What is digestion and its types?

Digestion is often broken down into two types: Mechanical digestion — food is physically broken into smaller parts. For instance, by chewing. Chemical digestion — food is broken down by acids and enzymes into its basic units.

What is the main function of the stomach?

Stomach. The stomach is a hollow organ, or “container,” that holds food while it is being mixed with stomach enzymes. These enzymes continue the process of breaking down food into a usable form. Cells in the lining of the stomach secrete a strong acid and powerful enzymes that are responsible for the breakdown process.

Which occurs during digestion quizlet?

What occurs during digestion? During digestion, food travels through the mouth, esophagus, stomach, and small intestine. Mechanical digestion and chemical digestion are the two processes by which food is reduced to molecules that can be absorbed.

Which occurs during digestion the mouth only allows for physical digestion?

The mouth only allows for physical digestion. The mouth only allows for chemical digestion. Chemical digestion prepares the food for physical digestion.
