The four stomachs (or compartments) are in the following order:
omasum
Giraffes, like cows, are ruminants. They have a four-compartment stomach which can pass partially digested food around to aid the digestion of plant matter. The final stomach compartment, called the abomasum, is the closest equivalent to the stomach of a monogastric animal such as a human.
Ruminants have a compartmentalised stomach. There are 4 compartments, the rumen, reticulum, omasum and abomasum. A non ruminant does not have a compartmentalised stomach, the non ruminants stomach has similar fucntions to that of the abomasum in the ruminants
The abomasum is the 'true stomach' of ruminants, such as cows and sheep. It is the only glandular section of their stomach - and is acidic (it is very similar to the simple stomach of monogastrics, such as pigs).
The first division of the stomach of a ruminant animal, in which most food collects immediately after being swallowed and from which it is later returned to the mouth as cud for thorough chewing. Also called paunch.
reticulum
Like all deer, moose are ruminants. Ruminants only have one stomach. However, the confusion comes from the fact that the stomach of a ruminant is divided into four chambers.
A fore-gut fermentor is the same name for a ruminant. Ruminants have a compartment where the feed they eat is fermented that is located prior to their true stomach, being the abomasum. Because the Abomasum is the true stomach and the other three chambers are more or less an extension of the esophagus, this is why ruminants are called fore-gut fermentors. Ruminants include such animals as cattle, sheep, goats, deer, bison, buffalo, yak, elk, moose, etc.
They do not. Cats do not "chew their cud".
Dogs are monogastrics. Cows are ruminants. Monogastrics have one simple stomach: Ruminants have a complex four-chambered stomach.
The digestive system of ruminants consists of four stomach.
It is proof that the conclusion that "all animals that are cloven hooved (or have 'two toes') are ruminants" is false. Swine are not ruminants because they have a simple stomach, not a four-chambered stomach, and thus are omnivorous animals. Other animals that are two-toed or cloven-hooved but are not ruminants are camelids (camels, alpacas, and llamas, for example), which are known as pseudoruminants due to the fact that they only have a three-chambered stomach.
