Description
This unit examines the human digestive system, including the roles of tissues, organs, enzymes, and beneficial bacteria. It also focuses on evaluating risks, interpreting data, identifying patterns, and suggesting improvements to enhance the reliability of investigations.
This unit builds on pupils’ prior learning from Diffusion, where they explored how substances move in and out of cells. It deepens their understanding by examining the human digestive system, focusing on how nutrients are broken down and absorbed through diffusion into the bloodstream. This prepares pupils for the next unit, Breathing and respiration, where they will apply their understanding of diffusion to explore gas exchange in the lungs, further connecting the role of diffusion in vital body processes.
