In most ethnic groups, levels of lactase in the small intestine decrease after weaning. In adulthood, consumption to too much dairy product often leads to intestinal distress (nausea, pain, diarrhea, & gas). Explain how a deficiency in the levels of lactase causes intestinal distress. (What normally happens to lactose? What happens to the lactose if lactase is isn’t present) Describe how the features of the mucosa of the small intestine (plicae circulares, villi, microvilli) relate to the function of the...
