chemical digestion begins. First the food is physically broken down by the mechanical process of mastication (chewing)‚ into smaller particles‚ creating a bolus with the tongue against the soft plate. During this phase‚ the salivary glands mix the food with salivary amylase beginning the chemical digestion of starches. The bolus then enters the pharynx (throat) first then is routed to the esophagus. These two tubes are simply passageways for the food to be carried to the holding tank‚ known as the

harmful‚ it creates substances that are necessary and it disposes of waste products. Function of the Pancreas * The pancreas is an important component of the digestive system. It manufactures and secretes digestive enzymes such as amylase‚ which digests starch. It also produces lipase‚ which breaks down fats‚ and trypsin‚ a protein processor. The pancreas creates and secretes insulin‚ glucagon and other hormones. Insulin and glucagon are especially important for the maintenance of blood sugar

The human digestive system consists of the gastrointestinal tract plus the accessory organs of digestion (the tongue‚ salivary glands‚ pancreas‚ liver‚ and gallbladder).[1] In this system‚ the process of digestion has many stages‚ the first of which starts in the mouth. Digestion involves the breakdown of food into smaller and smaller components‚ until they can be absorbed and assimilated into the body. Chewing‚ in which food is mixed with saliva begins the process of digestion. This produces a bolus

The study aims to answer the following questions: 1) Will the eggshell be an effective substitute for chalk? 2) Are there any similarities between the composition of an eggshell and a chalk? 3) Does the flour and starch affect the effectiveness of eggshell as a substitute for chalk? C. Statement of the Hypotheses: 1) There is a significant difference between the eggshell chalk and the commercial chalk. 2) There is no significant difference between the eggshell

The process? We rip away the food with our canines‚ bite it into small chunks with our incisors and grind the food with our molars/pre-molars. This process stimulates the exocrine glands in the mouth to release digestive enzymes such as salivary amylase‚ which aids in the break down of the food‚ particularly carbohydrates. Chewing the food also causes the release of saliva‚ which helps condense food into a bolus that can be easily passed through the esophagus to the stomach. When? This

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
