It is made up of a series of muscles that coordinate the movement of food and other cells that produce enzymes and hormones to aid in the breakdown of food. Along the way are three other organs that are needed for digestion: the liver, gallbladder, and the pancreas.
Digestion Begins. Enzymatic digestion occurs primarily in the mouth, stomach and small intestine. Both physical and chemical digestion begin in the mouth: the process of chewing grinds up food and mixes it with saliva, which contains an enzyme called salivary amylase. Enzymes facilitate chemical reactions by binding to reactive molecules.
