mechanical digestion - chewing, mixing, churning
chemical digestion - breakdown of fat, carbohydrate and proteins by specific enzymes (lipases, amylases, and proteinases respectively)
Chemical digestion
Chemical digestion and mechanical digestion
Mechanical Digestion (or physical digestion) is more about the mouth. It's chewing, biting, breaking down, and sofening the food. This is why its called "Mechanical" Digestion.Mechanical digestion involves the pulverizing and crushing of food particles, usually by chewing. Chemical digestion occurs through the secretion of digestive juices.
does absorption occur when mechanical or chemical digestion
Saliva begins the chemical digestion of starch. It also is important for the success of mechanical digestion of the mouth, but does not, in its own, perform mechanical digestion.
Mechanical and chemical digestion are not the same.
chemical digestion is breaking down with saliva, and mechanical digestion is chewing...(break down with chew!):):P

Mechanical digestion chops the food in to smaller pieces, thus exposing more of it to the enzymes of the chemical digestion.Mechanical digestion begins in the mouth by the teeth, tongue and saliva. Mechanical digestion is important for chemical digestion because when food is broken down into smaller particles by mechanical means, chemical digestion will be more efficient.
what is responsible for chemical digestion in earthworms
The tongue is involved in mechanical digestion.
