Which term describes chewing food; first stage of digestion?

Explanation:
The term describes chewing food and the first stage of digestion. In the mouth, the teeth, tongue, and jaw muscles grind and break down solids, increasing surface area and mixing them with saliva. This preparation forms a manageable bolus and kick-starts chemical digestion with saliva enzymes, setting the stage for swallowing and later nutrient breakdown. The other terms refer to liver-related conditions or storage molecules: hepatotoxins are substances that damage the liver, icterus is jaundice, and glycogen is the stored form of glucose. Thus mastication correctly describes the action described.
