Arrange the following stages of carbohydrate digestion and absorption in the correct sequential order from the mouth to the bloodstream: 1. Hydrolysis of starch into maltose by salivary amylase. 2. Breakdown of disaccharides into monosaccharides by brush border enzymes. 3. Inactivation of salivary amylase by gastric hydrochloric acid. 4. Active transport of glucose into enterocytes via sodium-glucose cotransporters (SGLT-1). Select the correct sequence:
