DIGESTION OF CARBOHYDRATES Digestion of carbohydrate begins in the mouth‚ with the secretion of the enzyme salivary amylase from the serous cells of the salivary gland. This enzyme breaks starch and glycogen into disaccharides. The mucous cells of the salivary gland secrete a mucus‚ which causes the food to stick together‚ and acts as a lubricant to aid in swallowing. The salivary glands are grouped into three categories: the parotid gland‚ submandibular glands‚ and sublingual‚ all located

food enters the mouth‚ digestion of the food starts by the action of mastication‚ a form of mechanical digestion‚ and the wetting contact of saliva. Saliva‚ a liquid secreted by the salivary glands‚ contains salivary amylase‚ an enzyme which starts the digestion of starch in the food. After undergoing mastication and starch digestion‚ the food will be in the form of a small‚ round slurry mass called a bolus. It will then travel down the esophagus and into the stomach by the action of peristalsis. Gastric

Solids clump toget her to form the cud or bolus. The cud is then regurgitated and chewed to completely mix it with saliva and

proteins are found in red meat/poultry; sources of carbohydrates include rice and wheat. Fats are found in dairy products. Carbohydrates are the main source of energy for the body; carbohydrates can be sugars‚ (monosaccharaides e.g. glucose) or starch. (Polysaccharides). Proteins are needed for repair‚ growth and repairing of the body. Fats are important for the absorption of vitamins and also in the forming of and insulating lair to keep the body warm.

for digestion‚ the salivary glands‚ teeth‚ tongue‚ liver‚ gall bladder and pancreas. The function of the digestive system is to breakdown food‚ so nutrients can enter the blood and lymph system. To start this process‚ we have to start with the mouth‚ when food is put in to the mouth you start the process of digestion‚ the structure of the mouth is made up of the lips‚ teeth‚ tongue‚ salivary glands‚ soft palate and pharynx. The lips function is to hold food in. The salivary glands‚ there are
