Best Answer: Probably the same as any other major... probably even shorter than some (such as pre-med), so 4 years. For my school, you need Intro, Research Methods ...
Digestion of foods in the small intestine. The small intestine continues the process of digestion and various enzymes are present there to break starches down further. These enzymes are called disaccharidases. The best known is lactase, which is the enzyme necessary to digest milk sugar. This enzyme is normally present in all young mammals who need this to digest mother's breast milk. With age and as breast feeding finishes, production of this enzyme ceases for life.
Several different glands produce digestive enzymes. The salivary glands in your mouth produce and secrete saliva, which contains the digestive enzyme known as salivary amylase. As food progresses to the stomach, two additional enzymes aid in the process of digestion: pepsin and gastric amylase.The pancreas secretes the three digestive enzymes known as pancreatic amylase, pancreatic protease and pancreatic lipase.In contrast to these enzymes, the liver produces bile salts and releases the substance to the gall bladder, which stores bile until you eat a meal.everal different glands produce digestive enzymes.
