Once digesta passes though the ileum into the large intestine, no enzymatic digestion occurs. Teeth seize, tear and grind food. This region is responsible for secreting mucus to line the digestive membranes to prevent damage from the low pH digesta as it passes to the small intestine. The diet of a pig is the diet of an omnivore which means they eat both plants and grains and animal protein. The numbers of the different kinds of teeth can be expressed in a dental formula.
Some animals fit both definitions of omnivorism, including bears, raccoons, dogs, and hedgehogs.

Carnivores usually have teeth that are specialised for dealing with flesh, gristle and bone. Swallowing is the first of these contractions.
