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
Yes stomach acid passes through the sphincter into the small intestine, but your small intestine secretes a mucus/solution that contains bicarbonate, a base.
This base mixes with the acid coming from
The stomach, neutralizing the stomach acid.
