===Pathology===

+

In severe cases, the [[The Rumen - Anatomy & Physiology|rumen]] almost fills the abdomen, the diaphragm is displaced forwards, compressing the lungs. The posterior vena cava is also compressed, reducing the venous return to the heart. Respiration is impaired and animals die from hypoxia.[[Image:oesophageal bloat line.jpg|thumb|right|150px|Oesophageal "bloat line" (Courtesy of Elspeth Milne)]]

** Posterior vena cava (lying dorsally) is also compressed, reducing the venous return to the heart.

−
