The Guttural Pouch is a mechanism for cooling the cerebral blood supply after exercise, due to its close connection with the internal carotid artery.
+
The function of guttural pouches is largely unknown, however hypotheses have been put forward:
    +
#It may influence internal carotid artery blood pressure. Air pressure varies with phase and forcefulness of respiration and the artery in the mucosal fold is exposed sufficiently to be affected.
 +
#Cerebral blood cooling mechanism. Operates at times of physical stress/exercise, when core body temperature is raised. Vigorous respiration, cool air in guttural pouches, and the exposed artery all lead to cooling of the blood.
