Question

Quizplus · Accepted Answer

Brush border enzymes break down carbohydrates and proteins, not fats. Fats are broken down by pancreatic enzymes and bile in the small intestine before being absorbed. They are then assembled into protein-lipid packages and transported via the lymphatic system through lacteals, which cannot enter the blood capillaries. Fats must also pass through the simple columnar epithelium lining the small intestines before entering the lacteals.
