This interactive PowerPoint covers a balanced diet, the role and importance of different nutrients, the digestive system, physical and chemical digestion, the role of bile, types of teeth, tooth structure, digestive enzymes and adaptations of villi for absorption. Worksheets require students to label the parts of the digestive system, identify four types of human teeth and complete a table describing their function and characteristics, label the parts of a human tooth and complete a table describing the function of key structures. Recommended time: 5-9 lessons. Relevant topics: Human nutrition, diet, digestive system, physical digestion, chemical digestion, absorption, body systems, and human physiology. Can be used to teach: IB, A Level, VCE, GCSE, IGCSE and KS3 Biology. Most suited to the IGCSE (Cambridge) specifications. Activity answers are included. File types included: PPTX and PDF Number of PowerPoint slides: 29
