To my understanding, when food is broken down in the stomach it turns into this stew of broken down food and HCL. When this sluree is being passed to the small intestine, how does our sphincter discriminate between the HCL and the food? And if it doesn’t, how does the small intestine stay intact without the stomach mucus?
In: Biology
The acid gets neutralized while it’s digesting food and it passes in largely alkaline intestine environment where the rest are reacted with bicarbonates. The sphincter is a muscle that keeps your stomach/anus closed, it’s not involved in digestion.
