While Pavlov was studying dog salivation he found that when a dog was fed dry food a high volume of saliva was created. When a dog was fed watery food less saliva was created. Along with this he discovered that when different items were put into a dogs mouth the dog only produced enough saliva to get the item out of its mouth. A marble took very little saliva sand took much much more saliva. Since every time the dog entered the lab it was going to be fed it would start salivating as soon as…

The production of saliva, is when α-amylase is secreted to start the digestion process (Bailey and Howard 1963). Glucose, maltose, malotriose are all low molecular weight products that that are formed through hydrolysis of amylase of internal α-1,4 and α-1,6-glycosidic linkages…

(lipids), and proteins. In the mouth mechanical digestion via the grinding of food between teeth and movement of the tongue help mix the food with fluid excreted by salivary glands in the mouth known as saliva. Saliva helps makes the food moist and easier to digest and sallow. More importantly saliva helps start the chemical digestion of food in the mouth because it contains various enzymes which help catalyze and speed up the breakdown of the macronutrients into their simpler components.…
