CULTURAL QA 01202417 Q2 How does the absorption rate of water differ in the small intestine compared to the stomach?
KR The Q and A is not clear; we are not Camels; stomach is not a storage; walls are so smooth, it needs to get itself protected from acids. So the facts are: Liquids typically leave your stomach quickly. For example, after you drink a glass of water, it's estimated that only 50 percent of it will be left in your stomach after 10 minutes. Solid foods often need to be broken down and liquified further, which means they usually take longer to leave your stomach Key Takeaways. Stomach pain after drinking water is relatively common and can occur for a variety of reasons, including habits like drinking water too fast, drinking water that's too cold, or chugging too much at once. The large quantity of gastric fluid produced by the mammalian stomach is thought to be secreted mainly by fundic glands in the mucosa of the stomach body. These glands contain mucus cells, chief cells and parietal cells that secrete mucus, pepsinogen and hydrochloric acid, respectively. After passing through the esophagus, the water arrives in the stomach. There, the water begins to absorb into the bloodstream. The water then moves into the small intestine, where nearly all the water is absorbed into cell membranes and the bloodstream As you drink water, it enters your stomach and is quickly processed through to your small intestine. The large intestine (colon) also absorbs some water. Nearly all the water is absorbed into the bloodstream from the small intestine When water enters the stomach, it does not significantly change the pH of the stomach acid, so there is no chemical reaction between the two. Additionally, the stomach lining has a protective mucus layer that prevents the acid from damaging the stomach tissue. ----------------------------------------------------K RAJARAM IRS 18124 On Wed, 17 Jan 2024 at 20:36, 'gopala krishnan' via iyer123 < [email protected]> wrote: > *CULTURAL QA 01-2024-17* > > *All the BELOW QA are from Quora digest to me on 17-01-2024.* > > * Quora answers need not be 100% correct answers * > > *.Compiled* *and posted by R.
