Answer:
connects the ileum with the asending colon to the large intestine
It is important to note that this is not an obligatory connection in many species. As far as function, it serves fermentation purposes in herbivores, allowing them to further digest fibers normally unavailable to them. Horses (and animals with similar digestive systems like rabbits) will have the most large and functional cecae, followed by ruminant and pseudoruminant animals (like cows and camelids, respectively). Obligate carnivores, like cats, will have the least functional cecae.
