A complete revision lesson covering the digestion section of AQA module B2- organisation. It also covers the two RPAs (enzymes and food tests) that occur in this topic. The lesson opens with the food tests RPA followed by looking at the components of a balanced diet along with the role of each nutrient in the body. The lesson then moves to look at the digestive system, its components and their individual role. It then looks at the stomach as an example of an organ with its tissues and their functions. The lesson the moves onto enzyme action and the enzymes of the human digestive system. It then covers the enzymes RPA before finishing with a series of exam questions.
