Which part of the fore gut holds up to 8-10 quarts?

The stomach is the correct part of the foregut that holds up to 8-10 quarts. In horses and other equines, the stomach plays a critical role in the initial stages of digestion, where food is mixed with gastric juices for breakdown. A horse's stomach is relatively small compared to other parts of its digestive system, but it can accommodate a significant volume, enabling the horse to manage its intake efficiently during feeding.

The capacity of the stomach allows for the digestion of large amounts of roughage, which is crucial for a horse's diet, as it typically consists of forage like hay and grass. Understanding this aspect of equine anatomy is vital for anyone involved in horsemanship, as it impacts feeding strategies and overall horse care.

While the cecum, small intestine, and mouth also play essential roles in the digestive process, their volume capacities differ significantly from that of the stomach. The small intestine is longer but has a different function and capacity, and although the cecum is a large fermentation site, it does not hold the same volume as the stomach when it comes to immediate food storage. The mouth serves only the purpose of intake and initial mechanical breakdown of feed.
