This note sheet encapsulates the digestive system covered in SL Biology. It outlines the digestive process in steps and the structure of the small intestine. It has details on the villus, structures of the villus epithelium, and all human digestive enzymes covered in the syllabus (amylase, protease, lipase). There are also details on macromolecule substrates that help to understand breaking down of starch, lipids, sugars, etc. Processes such as peristalsis and segmentation is also covered.
