Question

Did you know? In your small intestine there are tiny "fingers" (villi) that increase surface area. If you laid them flat, they cover 30 m² — half a tennis court. That's how a 6-metre intestine can absorb enough nutrients. In coeliac disease the villi get damaged; that's why absorption fails and gluten must be avoided.
