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: -This is the process where complex molecules like proteins, fats, and carbohydrates are broken down into smaller pieces that your body can use. It requires special proteins called enzymes. Movements. There are many movements that keep food going through your digestive system.

Detailed explanation-3: -As food travels from your mouth into your digestive system, it’s broken down by digestive enzymes that turn it into smaller nutrients that your body can easily absorb. This breakdown is known as chemical digestion. Without it, your body wouldn’t be able to absorb nutrients from the foods you eat.

Detailed explanation-4: -The fluid in your mouth is called saliva. Saliva plays an important role in chemical digestion. As the teeth break food into smaller pieces, saliva mixes with the food. Chemicals called enzymes, found in saliva, break down food into smaller pieces.
