Ok…here goes…Ahem…Ahem: I was just pondering wether or not the act of defication is helped along with lubrication. Does the anal canal, excrete some sort of lubrication to help the feces along out of the anus, or do the fecal packages themselves carry a lubricative surface?
Diarrhea, cha cha cha…
Mucus is produced in the rectum.
Nuf said?
Well, I was going to answer this, but I realized I’d just be pulling it out of my ass.
Here’s what I’ve gleaned from our anally obsessive SDMB community.
-
The rectal passage is lubricated by a think film of mucous.
-
The fecal packages, for which I certainly am NOT going to sign, are diverse in content and composition. If you eat jello, you’re likely to have a slicker movement than if you were eating, for instance, sawdust. Diet will also have an effect on how the log drops, if you will.
-
The really scientific name for the Rectal Passage is “Poop Chute”.
-
The reason a turd is tapered is to keep your ass from slamming shut.
But seriously, It’s your intestinal lining providing a layer of mucous, which I would actually think is for the protection of the intestine, rather than the greasing of the goods. Your diet just gotta have an effect too.
Here’s an experiment for you to try: go to the store. Get yourself a package of Preparation H, in suppository form. Slide one of those puppies up the old wazoo, and see if you have an easier time in the reading room.
IANAD. YMMV. CYPBTT.
Hmm…would it be the same mucus as the one produced in the nasal cavity and or the stomach lining?
Sorry Mr. Cynical, but the turd is tapered so you don’t get ‘splash-back’.
Mucus is mucus. There may be some minor differences in composition, but it’s basically the same.
Mucous, BTW, MrC, is different. It’s an adjective. You find mucus on mucous surfaces. No one wanted to know that, did they?
Damn! You mean this isn’t a discussion of novel ways to view home movies?

Oh. Nevermind. I thought this thread was about some type of map.
Well, I’m certainly glad that I’m not the subject matter (fecal as it may be) expert in this here thread. Where’s Coldfire when we need him?
Come on now, Everbody knows that turds are tapered so your ass won’t slam shut!
Just grateful to see that this wasn’t about a new variation on “ass-tral” projection.
Isn’t Astral Projection a Coil album?
An ass-imuthal projection?
Come to think of it, I’ve known many locations considered “the asshole of the universe”. I guess you center on one of them …
Nah, Coli.
Well, I’m glad the expert got his shit up here before people began to pull things outta their asses and making asses of themselves. Perhaps the asinine content of these jokes will get this shoved up the Ass of The SDMB, otherwise known as The Pit. Of course, if someone were to ass a real question, like how to bake brownies, we could salvage this steaming pile of crap. Ah well, the maggots will be here soon. Ass pudding and butt sausages are their favorite foods.
Boy, I wonder what crawled up Derleth’s ass and died 
Apologies to all. At the time, I thought it was a gas. I admit, I was pooped, really wiped out, and just needed to sit down awhile. Before anyone starts calling me a dirty bum, taking pot-shots at me, and I get throne out of here, I’ll head off behind the rear flank. That was a relief to unload. Thanks.
I consider it more likely that the turd is tappered to prevent the ass from slamming shut. Splash-back was not part of our evolution. Does anyone know long long humans have been pooping in water-containing toilets?
