Hard to say, but on a microscopic scale, probably the cells lining the digestive tract that produce acids for digestion of food. In order to create the high acidity in the stomach, these cells need to have a corresponding highly basic (high pH) region within their cells. While this high-pH area is very tiny, and does not last long, it may indeed be the highest pH in the body.
