The Digestive system
, Why we need the digestive system?
The food we eat is mostly in the form of very large particles.
These large particles need to be broken down to smaller particles before they can
fit in the blood or travel through the cell membranes.
Digest: to break down large food particles to smaller ones.
, Human digestive system
Amylase is an enzyme that breaks starch down to a
sugar, maltose.
An enzyme is a chemical, found in living organisms, that
speeds up chemical reactions.
Peristalsis is a muscular movement that only occurs in
the muscles of the digestive system. It is used to push
the food along the system.
