Why are the differences in the pH of the mouth stomach and small intestine important for digestion?
Crystalgutierrez92
The saliva need to be gentle enough at 7 pH to make foods small enough to swallow safely. The stomach needs to have strong acidity, at a 1 or 2 pH, to break down proteins into amino acids. The small intestine is where almost all of the absorption of the smaller portions are absorbed into the blood. The normal pH of the blood is close to 7 so the pH of the small intestine is 7.4.
