How many stomachs does a cow have?
It is a popular misconception that cows have four stomachs. Cows and many other artidactyls (two-toed hoofed mammals) including deer and goats are ruminants. This means that they digest food mainly in the stomach (as opposed to horses which mainly digest food in the large intestine). A cow does not have four stomachs, its stomach is merely split into four compartments called the Rumen, Reticulum, Omasum, and Abomasum. Their digestion is rather complicated and you could do your own research on it but essentially having four chambers helps break down cellulose, which is a component of grass that is hard to digest. In other words, cows have one stomach.
