The guttural pouches are paired ventral diverticulae of the eustachian (auditory) tubes, formed by escape of mucosal lining of the tube through a relatively long ventral slit in the supporting cartilages. The auditory tube connect the [[Nasal Cavity - Anatomy & Physiology|nasal cavity]] and [[Ear - Anatomy & Physiology#Middle Ear|middle ear]] and the diverticulum dilates to form pouches which can have a capacity of 300-500ml in the domestic horse. The pouches are normally aair filled.
