Verified step by step guidance1
Understand the term 'polygastric': In anatomy, 'polygastric' refers to an organism having multiple stomach compartments.
Identify the types of digestive systems: The options given are pseudogastric, monogastric, avian, and ruminant digestive systems.
Define each digestive system: A monogastric system has one stomach, an avian system is specific to birds, and a ruminant system has multiple stomach compartments.
Relate 'polygastric' to the digestive systems: Since 'polygastric' means multiple stomachs, it aligns with the ruminant digestive system, which is known for having four compartments.
Conclude that the ruminant digestive system is the correct answer as it matches the definition of 'polygastric'.
