AlexSlater1234567 Posted February 11, 2022 Posted February 11, 2022 Hello, is it true that chyme (the liquid result of hydrochloric acid in the stomach breaking down our food) can solidify again into feces? I was under the impression that we don't have a freezer in our stomach, so there's no way it would solidify again right?
CharonY Posted February 11, 2022 Posted February 11, 2022 I mean, what else would become feces but what we ingest? Note that food does not liquefy in your stomach. It gets partially digested and mixed up, but it is mostly a pulpy mess. As this liquid pulp travels through our intestines, excess liquid gets re-absorbed by our intestines.

If you leave a chicken leg or even a fish skull in a beaker of hydrochloric acid (in addition to the hydrofluoric acid I believe and one other we have in our stomach), in 3 hours time or less it will be all liquid. That's what chyme is! A thick foamy liquid. When the acid reacts with the fats though, we just get a kind of globby pudding fat because the hydrogen part of it doesn't mix with oil (like oil and water). So the liver bile is meant to dissolve it into droplets in the intestine. The bulk of food breakdown doesn't happen in the intestine, it happens in the stomach!

Concentrated HCL has a molarity of ca. 12M whereas the concentration in our stomach is ~0.15M. Also, I am pretty sure that even in concentrated HCl it will take quite a bit longer than a few hours to dissolve bone.

Remember we grow stronger with age, a grown man or woman can easily disintegrate a whole meal. The stomach muscles have to flex constantly to keep churning the food around. I was referring to the acid in a beaker that was just simply left by itself on a table. That is not our body, and we have also enzymes that are made to help speed up the process. How else does the chyme go through the tiny strainers of the intestinal wall? it needs to be fine enough to go in. If we release more food than we're taking in, we won't be growing the way we're supposed to. We're SUPPOSED to get bigger and fatter when we eat food! Bodybuilders eat well over 3 meals a day and the key is to burn it all off with a fast metabolism! We're consuming machines, that simply take in everything around us. ANY food group if looks yummy enough should contribute to your body size. It's not fair that you only get HALF the consequences of eating :D. EDIT: We also have a lining inside our stomach that prevents the acid from eating away at our stomach wall. God put us on this planet to survive and be happy, surely the system works Edited February 11, 2022 by AlexSlater1234567
John Cuthber Posted March 3, 2022 Posted March 3, 2022 A large part of the job of the colon is to remove water from the gut contents before they are expelled. If it doesn't do its job, you get the runs. Stomach acids will not attack, ceramics, glass or most plastics or even some metals, such as copper. They don't even destroy tomato pips.
