Answer 1

Answer:

Saliva is created when food is in the mouth.

Explanation:

The mucus component of saliva is secreted throughout the day to moisturize the lining of the mouth and increases during eating to lubricate the food in the mouth and assist with swallowing. It is secreted by the buccal glands of the mouth as well as the sublingual and submandibular glands. A salivary gland is a tissue in our mouths that expels saliva. You can feel your salivary glands activate when you eat something really sweet. As exocrine glands, they expel saliva into our mouths by way of ducts. Each day, our glands produce as much as a quart of saliva.
