What is the process of eructation?

Eructation refers to the release of gas from the digestive tract, which often occurs as a burp. This process typically happens when air swallowed while eating or drinking is expelled from the stomach. When the stomach fills with gas, it creates pressure that leads to the release of this gas through the mouth. Understanding this process is important in veterinary medicine, as it can be an indicator of digestive health in animals. For example, excessive eructation may suggest digestive disturbances or underlying gastrointestinal issues. The other options relate to different functions and processes in the digestive system but do not define eructation specifically.
