B10 - Nervous System

Independent Learning

Introduction

Cells in the body can only survive within narrow physical and chemical limits. In this unit you will look at what needs to be controlled and the systems used to control it. You will then move on to look in more detail at the nervous system and the fast and sometimes automatic responses it can generate. Students in set one will also study the basic functions of two incredibly complex organs: the brain and eyes.
