Answer:
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. ... Now in the form of large and small molecules, the food undergoes mostly chemical changes.
Explanation:
Food is chemically changed in digestion when new, smaller substances are formed. These chemical changes are examples of chemical digestion. Chemical digestion begins in the mouth when enzymes in saliva begin to break down carbohydrates
Explanation:
The stomach is a muscular organ located on the left side of the upper abdomen. The stomach receives food from the esophagus. As food reaches the end of the esophagus, it enters the stomach through a muscular valve called the lower esophageal sphincter.
The stomach secretes acid and enzymes that digest food. Ridges of muscle tissue called rugae line the stomach. The stomach muscles contract periodically, churning food to enhance digestion. The pyloric sphincter is a muscular valve that opens to allow food to pass from the stomach to the small intestine.
