The stomach of the cow is a remarkable organ. It has four compartments (rumen, reticulum, omasum, and abomasum), each designed to perform certain functions. www.doesgodexist.org
Cows graze most of the day and eat large amounts of food. Cows have four stomach compartments. One of these stomachs is called the rumen. It is designed to help these grass-eating animals digest their food. To get most possible nourishment out of grass, cows regurgitate their food and then chew it again. This called chewing the cud. There is also a special bacteria in the rumen to help with digestion.
Cautious is quite correct. Cows are ruminants, which generally have four stomachs, however Camels and some others only have three. The first stomach is called the Rumen which softens the food initially, it then gets regurgitated as "cud" then once swallowed goes to one of the other stomachs. The other stomachs are called: the reticulum, omasum, and abomasum. Hope that clears this up for you MadBiker
Cow has only one stomach. But it had four compartment, food goes through all the four that is rumen, reticulum, omasum and abnormal before it come out as a waste. (but it is not a waste)
