GENERAL HISTOLOGY

Detailed explanation-1: -Mechanical digestion involves physically breaking down food substances into smaller particles to more efficiently undergo chemical digestion. The role of chemical digestion is to further degrade the molecular structure of the ingested compounds by digestive enzymes into a form that is absorbable into the bloodstream.

Detailed explanation-2: -Mechanical digestion This refers to involuntary contractions and relaxations of the muscles of your esophagus, stomach, and intestines to break down food and move it through your digestive system.

Detailed explanation-3: -The digestive system converts the foods we eat into their simplest forms, like glucose (sugars), amino acids (that make up protein) or fatty acids (that make up fats). The broken-down food is then absorbed into the bloodstream from the small intestine and the nutrients are carried to each cell in the body.

Detailed explanation-4: -There are 2 types of digestion: mechanical and chemical digestion. 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-5: -Examples of physical digestion, also known as mechanical digestion, are the act of chewing, as well as peristalsis in the stomach.
