Digestive system of the horse
What system of the horse is complicated and digests food? If you said the digestive system, you’re correct. If you guessed the solar system, you aren’t. The first part of the digestive system is the mouth. The lips grab the food, which is called prehension. Once in the mouth, the teeth crush, grind and tear the food, which is called mastication, otherwise known as chewing. The salivary glands produce saliva, which softens it. Next, it goes down the esophagus. At the bottom of the esophagus, it goes through the cardiac sphincter, which is very strong, which makes it so the horse can’t throw up, to the stomach, where it gets churned with digestive juices, then it goes through the pyloric sphincter to the small intestine, which is split into three parts: the duodenum, the jejunum, and the ileum. Most of the digestion of nutrients occurs here, since it’s the longest part of the digestive tract, 70 feet. Off to the large intestine it goes, which is composed of the cecum, the large colon, and the small colon. Finally, it goes to the rectum and gets expelled through the anus. This complicated system is a testimony to our wonderful creator, who created the whole solar system, which is, by the way, not in the horse. ;)
