regurgitation

Regurgitation is the act of casting up incompletely digested food, often seen in biology when animals feed their young. For example, some birds regurgitate partially digested food to their chicks. This process is also crucial for ruminants, such as cattle and sheep, which have a four-chambered stomach. They store ingested plant material in the rumen, then regurgitate it as cud to chew again, aiding in the breakdown of cellulose. Some social insects, like termites, also produce stomodeal food, which is partly digested food regurgitated to feed colony members. The term can also be used figuratively to describe restating acquired information.12345
