The Large Intestine

 The large intestine is the last part of the digestive tube. It receives material from the small intestine and extracts the last remaining useful substances from it.

The cecum is a blind ended sac. In carnivores it is small, but in monogastric herbivores, such as the horse, it can be quite large. It acts as an important part of a horse's microbial fermentation chamber.

The colon is the longest part of the large intestine.

The rectum is the final segment of the large intestine. From here the contents move out through the anus during defecation.
