Biology KS2 / KS3: What a human stomach looks like
Dr Chris visits an anatomist to take a close look at the digestive system of a human.
The stomach can stretch to hold approximately one litre of fluid or food.
The small intestine is examined and the role of this organ in digestion and absorption is described, and the importance of the impressive blood supply.
Dr Chris then describes the villi and their role in absorption.
Key Stage 2
Ask students to list the organs in order during the passage through the digestive system, and next to each one to say what its major roles are.
After watching the clip, they can self or peer assess their work.
Key Stage 3
Before watching the clip, ask students to list in order the organs in the digestive system from memory, and what their major functions are.
After the clip, students can research the adaptations of the digestive system that maximise absorption of the nutrients.
This clip will be relevant for teaching Biology/Science at KS2 and KS3 in England Wales and Northern Ireland. Also at 2nd and 3rd Level in Scotland.
