Digestion In Horses

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 …show more content…
This style of digestion is somewhat of the inverse of hind-gut fermentation. There is a large fore-gut where the majority of digestion occurs that is then followed relatively smaller hind-gut. For this process to work ruminants are an equipped with a polygastric stomach which is separated in to four distinct sections by membranous structure with in the stomach. Following the transport of digesta first there is the rumen the larges part of the stomach being able to hold as much as 50 gallons of fluid and for which this style of digestion is named for. Continuing along next digesta will pass in to the reticulum which is actual more cranial than the rumen. Next digest will in to the omasum and then on to abomasum. From which is then passed on the dudenum in the small …show more content…
Where this may not seam like a big deal, do to this technique of eating now and chewing later cows do not differentiate well between food and no food items. This will often cause them to swallow small pieces of metal if found in their food. Such as nails, wire, or bolts which can then puncture the reticulum causing it to leak. This will then lead to an infection of the peritoneum.

Once the digesta is sufficiently broken down and fermented to allow the utilization of the nutrients it will pass in the omasum. The part of the stomach that acts as a sort of gate way between the fermentation digestion of the rumen and the glandular digestion of the abomasum. This act is performed by a series of large folds in the omasum that only allow small particles though. Returning any larger particles to the rumen for further digestion. Due to these fold the omasum despite it being the smallest of the four sections it contains around 30% of the surface area of the

    The small intestine is a long muscular tube that releases enzymes to further break down the molecules. There are three sections to the small intestine, the duodenum, jejunum, and ileum. The continuous break-down process is mainly achieved in the duodenum, while the jejunum and ileum provide the bloodstream with nutrients. Once the content has passed through the lower intestine, it has transformed from a semi-solid state to liquid form due to the break-down process and the enzymes released. 5.…

    The teeth are designed to cut, tear, or grind food to help aid in the digestion process. After the mouth, the next component to digestion is the pharynx. “The pharynx consists of the nasopharynx, oropharynx and laryngopharynx” (Johnstone, et al, 2014). Once the food has entered the pharynx, swallowing is now an involuntary muscle movement, and the food continues to the Esophagus. “The oespphagus is a muscular tube, abouto 25cm long with a diameter of 2 cm, which starts at the laryngopharynx and ends at the stomach, and is a passageway for food” (Johnstone, et al, 2014).…

    The two sphincters in the esophagus aid with the entrance of the food bolus and the exit of the food into the stomach. The food bolus enters the stomach where the protein in the turkey and cheese are broken down by pepsin and HCI that break the protein to polypeptides. The fat within the cheese and the turkey and bread are broken down by tributyrinase to tributyrin to glycerol and fatty acids. The stomach issues for the storage, mixing and controlled emptying of food. There is a sphincter at the end of the stomach called the pyloric sphincter that controls the food from entering the small intestines.…

    Most of the water from chyme is absorbed via osmosis while in the small intestine as well as nutrients thus changing it into fecal matter. Segmentation moves intestinal contents through the ileum toward the ileocecal valve. At the late intestinal phase segmentation ceases and duodenal mucosa releases motilin which initiates peristalsis. Ileocecal sphincter relaxes and chyme passes through into the large intestine. Valve flaps close via backward pressure as chyme goes into large intestine.…

The cecum is the first part of the large intestine and has the appendix attached to its inferior portion. The appendix is located in the right lower quadrant of the abdomen and measure eight to ten centimeters in length, six millimeters in diameter, and two millimeters in wall thickness. From the cecum, the colon courses superior which is known as the ascending colon, which in turn, becomes the transverse colon, and finally the colon returns inferior as the descending colon and slightly courses medial as the sigmoid colon. The rectum leads into the anus.…
