serve an important function by regulating pressure on the eardrums
auditory tubes
The exercising horse generates a tremendous amount of heat because of the massive amount of muscular work required for high-speed motion. T/F
true
Because the horse spent much of its evolutionary development on flat grassland, pressure regulation appears to be a factor in explaining the extreme size of the equine guttural pouch. T/F
