Humans, like members of many other mammalian species, are monogastrics, which means that they have a single-chambered stomach. Some other mammalian species, though, are ruminants, which means that their stomachs have four chambers instead of one. Ruminants are perhaps most well-known for how much chewing they do during their digestive process. When a ruminant, such as a deer, eats food, the first two chambers of the animal's stomach extract the liquid from the food. The solid remainder of the food, known as the cud, is then regurgitated back into the animal's mouth to be chewed again. This allows the animal to extract more nutrients than it would otherwise. This is ideal for animals that eat plant-based diets, so it's no coincidence that ruminants are always herbivores.
