Cows are ruminants, which means they have a Rumen (one part of their stomach), which is basically a big fermentation vat. There are microbes that ferment and break down cellulose.
When food is in the rumen, the bacteria digests the fiber, turning it into volatile fatty acids, proteins and B vitamins. Because the rumen boasts a good blood supply, these nutrients are easily absorbed for use by the body. After this part of the digestive process, the "digesta," as the food is termed, heads to the reticulum.
People are monogastrics, which means they only have one stomach, and cannot digest.
