hunger and appetite are two major components of the cephalic phase of digestion‚ which is the stimulation and release of digestive juices in preparation of the food. Once inside the mouth‚ my teeth and salivary enzymes help to break down the food components into smaller molecules. This chemical amylase in our mouth helps to start breaking down the food chemically in order to fully be able to absorb all nutrients in the later process. The resulting product after all the food’s been chewed is called the

of the alimentary canal‚ which is the long tube within our bodies that starts with the mouth and ends with the anus (“Human Nutrition‚” 2011). It also consists of our salivary glands‚ as well as the pancreas and the liver. My saliva is set in the flow of a motion by my brain reflex that sets in whenever I see or smell food. Amylase is an enzyme that breaks starch down into sugar. It is often present in human saliva‚ where it begins the chemical process of digestion (Princeton University‚

these parts help in the digestion of food. Digestions start from the mouth. Firstly‚ ingestion is the process of taking food via the mouth. When the food enters the mouth the food is then chewed‚ mixed with salivary gland‚ which produces and enzyme called salivary amylase. This enzyme breaks the food

Upon ingesting food into the mouth‚ salivary glands secrete saliva which contains the digestive enzyme ‘Salivary Amylase’. This has a neutral pH and
