View of a cow's digestive track:
1. The Rumen - this is the largest part and holds upto 50 gallons of partially digested food. This is where the 'cud' comes from. Good bacteria in the Rumen helps soften and digest the cow's food and provides protein for the cow.
2. The Recticulum - this part of the stomach is called the 'hardware' stomach. This is because if the cow eats something it shouldn't have like a peice of fencing, it lodges here in the Recticulum and cause no damage to the cow. Also, the grass that has been eaten is also softened further and and formed into small wads of cud. Each cud returns to the cow's mouth and is chewed 40-60 times and then swallowed properly.
3. The Omasum - this part of the stomach is a 'filter'. It filters through all the food the cow eats. The cud is also pressed and broken down further.
4. The Abomasum - this part of the stomach is like a human's stomach and is connected to the intestines. Here, the food is finally digested by the cow's stomach juices and essential nutrients that the cow needs are passed through the bloodstream. The rest is passed through to the intestines and produces a 'cow pat'.
