GENERAL HISTOLOGY

Detailed explanation-1: -Mechanical digestion in the oral cavity consists of grinding of food into smaller pieces by the teeth, a process called mastication. Chemical digestion in the mouth is minor but consists of salivary amylase (ptyalin, or alpha-amylase) and lingual lipase, both contained in the saliva.

Detailed explanation-2: -Mechanical digestion begins in your mouth with chewing, then moves to churning in the stomach and segmentation in the small intestine. Peristalsis is also part of mechanical digestion.

Detailed explanation-3: -In mechanical digestion, food is physically broken down into smaller pieces by tearing, slicing, churning and mixing. In chemical digestion, chemicals produced by the body break down food into very small pieces.

Detailed explanation-4: -Mechanical digestion is the conversion of food into smaller pieces through physical means such as mastication, peristalsis, and segmentation.
