Blood in the villi helps to absorb nutrients and sugar
molecules.
Nutrients from food are absorbed.
Fat is broken down into smaller droplets.
Most of the digestion that occurs in the small intestines
occurs in the duodenum, which is the first part of the small intestines. This is
where fats are broken down into smaller droplets
by emulsifiers and lipases. Absorption takes place in the other parts through the
villi.
