What is regurgitation in animal anatomy

Answer 1

Regurgitation is the process by which some animals bring previously ingested food back up from their digestive system. This can occur for various reasons, such as to re-chew and re-digest food for better nutrient absorption, to feed their young, or as a defense mechanism to deter predators. Some animals, such as birds, reptiles, and certain mammals, have specialized structures in their esophagus or crop that allow for regurgitation.
