If you are studying GCSE Science, or A Level Biology, you need to know all about osmoregulation, how our body maintains the same levels of water. To help you understand osmoregulation, check out Part 3 of our “How to” revision guide on Homeostasis.
This guide will help if you are studying for GCSEs, and is also suitable for A Level students, as sections of the guide go “beyond GCSE”. It includes some example GCSE and A Level questions with answers at the end, so you can check your understanding of osmoregulation.
