A ruminant's digestive tract has 4 sections to its stomach. Because the plant matter that most ruminants enjoy is hard to digest, ruminants have to regurgitate food to chew it again (e.i., "chewing the cud"). The four stomachs allow the hard-to-digest food to be digested many times.
The digestive system of ruminants consists of four stomach.
Wolverines have a digestive system that is similar to other carnivores. The stomach is not divided into chambers like you would find in ruminants.
Ruminants digestive systems are adapted to ensure survival as it allows them to consume a wide variety of vegetation. More robust plant material has plenty of time to break down so that the nutrients can be fully absorbed by the body.
Ruminants such as cattle have four compartments to their stomachs. Moving oral to aboral, they are the rumen, the reticulum, the omasum and the abomasum.
They do not. Cats do not "chew their cud".
They don't. Cows only have one digestive system. They do, however, have a stomach with four chambers. Perhaps that is where you are getting the four-something from as far as bovine digestive physiology is concerned.
Dogs are monogastrics. Cows are ruminants. Monogastrics have one simple stomach: Ruminants have a complex four-chambered stomach.
It can digest roughage that any other animal (except other ruminants like sheep and bison) would simply starve to death on.

You are not going to get that "long answer." A cow's and human's digestive system is NOT the same, I don't care how you try to go about it. Yes they are similar in function, by the fact that they both break down and digest food or feed to more manageable and smaller molecules to be absorbed into the body via blood stream to the zillion cells that are in the body, but they are not the same in what is digested and the whole processes that set a cow's digestive system apart from that of a human's.
