Mucosas contain glands which release, you guessed it, mucus. Dr Bulsiewic explains that this special mucosa in your anal gland can sample what’s going on and tell your body if it’s gas or poo (and whether it’s safe to release). Well, scientists don’t actually know – some think that because your anal canal is sensitive to temperature, this might be the key in deciding what you’re producing. Your anal canal is also full of sensory nerve endings, so the consensus is that the mucosa takes a sample, these nerve endings are alerted, they decide what they’re dealing with and voila, you can decide whether to sneak a fart or run to the loo.
