likoan [24]

Answer:

We begins to digest the carbohydrates the minute the food goes to our mouth. The saliva which is secreted from our salivary glands moisten up the food when it is chewed. Salivary amylase is present in our saliva which begins the breaking process of sugars in the carbohydrates when we are eating.  It is also referred to as ptyalin. Salivary glands are exocrine glands which makes saliva through a ductory system.Humans have three major paired salivary glands ( parotid, submandibular & sublingual)as well as hundreds of minor salivary glands.
