*Water intake lowers the ruminal temperature so bacteria are tolerant to temperature changes towards the lower end of the scale

*Objects are often lodged in the rumino-reticular fold. When the rumen contracts, the object can be pushed through the [[The Reticulum - Anatomy & Physiology|reticulum]] wall into the [[Structure of the Heart - Anatomy & Physiology#Pericardium|pericardium]] and [[Heart - Anatomy & Physiology|heart]].
