This unit is part of the bigger Topic 6 of the syllabus.  In this section we need to be able to:

  • Explain why digestion is necessary, and what role enzymes play in digestion.
  • Draw and label a diagram of the human digestive system.
  • Outline the functions of the main parts of the digestive system.
  • Distinguish between absorption and assimilation.
  • Relate the structure of the villus to its function.

The syllabus guide is here: Topic-6-syllabus-outline

Some excellent resources to help us through this unit.  Here, here and here.

We’ll also do a dissection of animal intestines, so look forward to that!  When else will you have the opportunity to put your hand inside a goat’s stomach or simulate peristalsis with real intestines?
