MICROANATOMY

Detailed explanation-1: -Digestion is the process of mechanically and enzymatically breaking down food into substances for absorption into the bloodstream. The food contains three macronutrients that require digestion before they can be absorbed: fats, carbohydrates, and proteins.

Detailed explanation-2: -Digestion is important for breaking down food into nutrients, which the body uses for energy, growth, and cell repair. Food and drink must be changed into smaller molecules of nutrients before the blood absorbs them and carries them to cells throughout the body.

Detailed explanation-3: -The process by which your body breaks down food into small nutrient molecules is called digestion. There are two kinds of digestion – mechanical and chemical. In mechanical digestion, foods are physically broken down into smaller pieces.

Detailed explanation-4: -Mechanical digestion occurs as layers of muscle in the stomach lining contract to produce a mixing and churning motion. Chemical digestion is carried out by stomach juices that contain enzymes and hydrochloric acid. When the food has been turned into liquid form, it moves onto the small intestine.
