The different compartments of the ruminant stomach develop from the foregut spindle in foetal life. During embyogenesis and after birth the [[The Abomasum - Anatomy & Physiology|abomasum]] is the largest of the compartments (over half of the weight and capacity of the four stomachs) due to the [[oesophageal groove|oesophageal groove]] directing milk from the oesophagus to the [[The Rumen - Anatomy & Physiology|rumen]] into the abomasum, bypassing the [[The Reticulum - Anatomy & Physiology|reticulum]].

* In most animals, after swallowing, food leaves the [[Oesophagus - Anatomy & Physiology|oesophagus]] and enters the [[Forestomach - Anatomy & Physiology|stomach]]. In ruminants, food enters the [[The Abomasum - Anatomy & Physiology|abomasum]] after fermentation in the forestomach.
