Explanation:
Detailed explanation-1: -Digestion begins immediately in the oral cavity with both mechanical and chemical digestion. Mechanical digestion in the oral cavity consists of grinding of food into smaller pieces by the teeth, a process called mastication.
Detailed explanation-2: -Humans and many animals have a monogastric digestive system. The process of digestion begins with the mouth and the intake of food.
