The term 'bovine stomachs' refers to the four-chambered stomachs of cows and other bovines. The four chambers are the rumen, reticulum, omasum, and abomasum. The rumen is the largest chamber and is responsible for fermentation of food. The reticulum is the second chamber and is responsible for sorting and storing food. The omasum is the third chamber and is responsible for further digestion and absorption of nutrients. The abomasum is the fourth chamber and is responsible for the final stages of digestion. The acronym MAWS stands for the four chambers of the bovine stomach: the rumen, the reticulum, the omasum, and the abomasum.
