The parts of the human digestive system
Lesson details
Learning outcome
I can describe parts of the digestive system and how they are adapted to digest food.
Key learning points
- Major organs of the human digestive system and the order in which food moves through them.
- The functions of the organs, tissues and glands of the digestive system and how they are adapted to break down food.
- Food that cannot be digested is passed out of the body as faeces.
Keywords
Digestion - Digestion is the process of breaking down food into substances that can be absorbed into the blood.
Digestive system - The digestive system is a collection of organs that break down food.
Gland - A gland is a tissue or an organ that produces chemicals.
Adaptation - An adaptation is a feature that helps an organism to function and survive.
Fibre - Fibre bulks up food so it can be moved through the digestive system more easily.
Common misconception
The role of the stomach is often misunderstood as the main or only place where digestion occurs.
The lesson explores the roles of the stomach and the intestines in digesting food and absorbing nutrients.
Teacher tip
In the third learning cycle you could choose between Task C parts 1 and 2, depending on the level of your students. You could also get them to create a model digestive system using straws, balloons, etc, to make it more engaging.

We use learning cycles to break down learning into key concepts or ideas linked to the learning outcome. Each learning cycle features explanations with checks for understanding and practice tasks with feedback. All of this is found in our slide decks, ready for you to download and edit. The practice tasks are also available as printable worksheets and some lessons have additional materials with extra material you might need for teaching the lesson.
The assessment exit quiz will test your pupils' understanding of the key learning points.
Our video is a tool for planning, showing how other teachers might teach the lesson, offering helpful tips, modelled explanations and inspiration for your own delivery in the classroom. Plus, you can set it as homework or revision for pupils and keep their learning on track by sharing an online pupil version of this lesson.
