The pouch: what a very useful structure!
By definition a “pouch” is a small sac-like container to store or keep things in. Biologically speaking, it is a pocket-like space in or on the body and the ‘pouches’ in our cheeks, for example, come to mind. They are useful for sucking up liquids (without these pouches as in the case of many carnivores like dogs and cats, liquids would have to be leapt up). —>—>
