Answer:
the process of digestion begins in the MOUTH.
Explanation:
Digestion of food begins in the mouth. Here, the food crumbles into pieces, and at the same time, it is soaked in saliva.
Saliva, in addition to the enzyme ptyalin, contains water and mucus, which makes it easier for food to glide when swallowed. Food in the mouth should be chewed for a long time and abundantly soaked in saliva.
Food in the stomach is decomposed by gastric juices, which are pepsin, chymosin, and gastric lipase. Hydrochloric acid gives the acidity necessary for the formation of pepsin, and in addition, sterilizes already mushy food.
