ANATOMY

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: -Chemical and mechanical digestion are the two methods your body uses to break down foods. Mechanical digestion involves physical movement to make foods smaller. Chemical digestion uses enzymes to break down food.

Detailed explanation-3: -Digestion is the mechanical and chemical break down of food into small organic fragments. In chemical digestion, enzymes break down food into the small molecules the body can use. Digestive enzymes are found in the digestive tracts of animals.

Detailed explanation-4: -The complex molecules of carbohydrates, proteins, and fats are transformed by chemical digestion into smaller molecules that can be absorbed and utilized by the cells. Chemical digestion, through a process called hydrolysis, uses water and digestive enzymes to break down the complex molecules.

Detailed explanation-5: -Enzymes break the food into nutrients, that are processed in the large and small intestines. The small intestine absorbs the nutrients and send it to the bloodstream. It also does most of the Chemical Digestion, while there is absolutely no Mechanical Digestion.
