GCE AQA BIOL - The Digestive System
Unit 3.1 Biology and disease
3.1.2 The digestive system provides an interface with the environment. Digestion involves enzymic hydrolysis producing smaller molecules that can be absorbed and assimilated.
In GCE AQA Biology, you’ll be expected to know about the human digestive system 🍽️. The entire digestive system is made up of a long, continuous tube (alimentary canal) and its associated glands and organs. Its function is to carry out digestion:
Digestion: Large, insoluble molecules are hydrolyzed by enzymes to produce smaller molecules that are absorbed and assimilated 🍔
The following is a labelled diagram of the human digestive system:
As a GCE AQA Biology student, you should be able to identify and label the following parts of the alimentary canal and its associated organs:
That's it for today! 🎉
