7. Which actions (MDSA) are performed in each tract of GIT?

# data[].attributes.body
In the oral cavity the motility is chewing and swallowing; the secretion is saliva and amylase; there's the carbohydrate's digestion and no absorption.
In the stomach the motility is peristalsis, propulsion and mixing; the secretion is HCl, pepsinogen and gastric mucus; it digests proteins and fats; it absorbs lipid soluble substances.
The small intestine absorbs all the macromolecules; the motility is mixing, propulsion and segmentation; it secretes CCK; it digests everything.
The large intestine's motility is segmentation and mixing; it secretes mucus; it digests nothing; it absorbs water ions and vitamins.
