pancreatic juices digest complex carbohydrates to oligosaccharides

brush border oligosaccharidases - lactase, sucrase-isomaltase and maltaserelease monosaccharides - digest the oligosaccharides into their monoscahharide components - glucose, galactose and fructose.

Glucose and galactose are absorbed through the Na co-transport - a type of active transport that utilise the sodium concentration difference between the gut and the cell.
