How are the chemical digestion and the mechanical digestion similar?

chemical digestion is breaking down with saliva, and mechanical digestion is chewing...(break down with chew!):):P

Mechanical digestion refers to the actual grinding / physical digestion in your mouth where your teeth cut and mash up your food. Chemical digestion refers to the enzymes that break up the food...

mechanical digestion - chewing, mixing, churning chemical digestion - breakdown of fat, carbohydrate and proteins by specific enzymes (lipases, amylases, and proteinases respectively)

The digestion process begins in the mouth. Chewing your food is a mechanical form of digestion. The saliva in your mouth begins to chemically break down your food, which is chemical digestion.

both mechanical and chemical digestion happen in your body
