Document Summary
Objective: the digestive tract of the horse is unique, understanding the key elements of the uniqueness will help explain how the horse is adapted to eating particular foods. It takes about 65-75 hours for feed to move from the mouth to the anus of the horse. Elements of the digestive system: mouth, pharynx, esophagus, foregut, stomach, sphincter at the top of the stomach (cardiac sphincter) is very strong, this means they cannot vomit which is important to know if they swallow anything poisonous. Anatomical location: all of the gi tract falls caudal to the diaphragm, abdominal pelvic cavities are lined with serosa. 2: serous membrane (serosa) covers the organs of the body so they are able to easily move around preventing injuries such as bowel twists, peritoneum, visceral, surface of organ, parietal, surface of abdominal wall. Mouth: grasping feed, moistening feed with saliva, chewing feed to reduce particle size.
