What is Regurgitation?
'''Regurgitation''' is the process of a [[human]] or [[animal]] letting out the food it had been [[digestion|digesting]]. Sometimes, [[blood]] can come out as well. Regurgitation can be very important to some animals, such as [[birds]] for example. It is used by a number of [[species]] to feed their young. This is especially when the young is in its nest or home and the parent hunts for food. Or some birds can occasionally regurgitate [[pellet]]s of food that is not digestable, such as [[bone]]s and [[feather]]s. [[Owl]]s are known to do this. {{science-stub}} [[Category:Physiology]]
