Intracellular- food is broken down when it is in the cell (engulfed by phagocytosis), nutrients are absorbed.
Extracellular- food is broken down with help of enzymes before nutrients are absorbed by/into cells.
This is done by most mammals, simple animals (such as flatworms) have a gastrovascular cavity, more complex mammals (such as humans) have an alimentary canal.
In humans, it takes place in different compartments (stomach, small intestine).
Extracellular dig. allows mammals to consume larger prey.
