While the location of the pouches is generally understood, their purpose is not. Currently, researchers believe the pouches serve to cool blood flow to the brain during extended strenuous exercise. ref http treatmentofdiseases.blogspot.com 2006 01 mysterious guttural pouch.html ref Due to the general inaccessibility of the pouches, they can be an area of infection by molds and bacteria, and these infections can be extremely severe and hard to treat.
