Pyloric Sphincta Ferentation In A Horse

Horses have a type of digestion that is called hind-gut fermentation a type of digestion characterized by a relatively small fore-gut and mid gut which digesta passes through fairly quickly. To the hind-gut where the majority of digestion occurs via microbiological forces. Staring out the digesta is swallowed into the stomach which in a horse is monogastric having only one chamber to it. That said, it is not the kidney bean shape that we would think of in humans or pigs, but it has a more pronounced curved shape making a kind of crescent shape. Do to this shape it can be divided into three regions of activity with can be classified by both acidly and condition of digesta. The most cranial section is the oesophgeal region where the oesophagus joins with the stomach at the cardiac …show more content…
Starting with the duodenum, the foremost portion of the small intestine. Separating the duodenum from the stomach is a sphincter called the pyloric sphincter. The pyloric sphincter by regulating the passage of digesta is able to both make sure that digesta spends enough time in the glandular portion of a stomch for full digestion. Furermaore by reguationg the flow if helps prevent digetive enzymes from passing in the small intestine where there they could damage the tissue of the intestine.

Digesta makes its way in the duodenum it is mixed with digestive bile. This bile has two major jobs first it is relatively alkali when compared to digestive enzymes. As bile is introduced in the duodenum, it is able to bring the pH of the digesta form a Ph of about 2-3 to a neutral normal pH of 7.0. Second bile is lipophilic attracting it the so far mostly undigested fatty acid chains in the digesta. Bile is able to attach to these chains facilitating their digestion and uptake by the small
