What did we learnt?
Adaptation of small intestines Small intestines Liver Fate of glucose in liver
HEPATIC PORTAL VEIN

Adaptations of the intestinal wall
One-cell thick epithelium
Numerous blood vessels to maintain
concentration gradient.
Increase Surface area

The four stages of Holozoic Nutrition
Stage Function
Feeding The intake of food into body
Digestion Breaking down of large food molecules into soluble molecules.
Absorption Process whereby digested materials are taken into the body
Assimilation Absorbed food are converted into new protoplasm to provide energy.
