digestion and absorption

microvilli

folded cell membrane

function of bile salts

emulsify lipids, increases surface area of lipid for increased lipase activity

describe digestion of starch

hydrolysis, of glycosidic bonds, to maltose by amylase, to glucose by disaccharidase

micelles 

during lipid digestion, bile salts form micelles containing monoglycerides and fatty acids 

micelles function

transport digestion products to the epithelial cells in the ileum, at the cell surface, micelles release monoglycerides and fatty acids, they can diffuse directly across the epithelial cell membrane because they are lipid-soluble
