What are difference of simple stomach animals from compound stomach animals?

Answer 1

Simple stomached animals, such as dogs, pigs and horses (and humans) only have one chamber in their stomach. It is generally at a low pH such as pH 2-3.

Animals with a compound stomach have a much more complex arrangement. They have four compartments to their stomach. These compartments are called the reticulum, the rumen, the omasum and the abomasum. The abomasum is similar to the simple stomach. THis arrangement is so the animal can ferment the food they eat. Animals with this arrangement are known as ruminants and include sheep, goats and cows.
