This section is split into six topics, which you can work through sequentially.

The aim of this section is to familiarise you with how the body normally controls blood glucose concentrations.

- T1: How the body decreases blood glucose concentrations after eating
- T2: How the body produces glucose when we are fasting
- T3: How does insulin act?
- T4: Other key hormones in control of glucose homeostasis
- T5: Summary
- T6: Test yourself

By the end of the section, you should be able to:

• Understand the different processes that the body uses to decrease blood glucose concentrations in healthy individuals
• Describe the key pathways that the body uses to increase blood glucose concentrations in fasting healthy individuals
• Describe what insulin is and what is does
• Outline other key hormones in these processes and how they work together
