SCN3230-ABED_1: Unit A Introduction

Introduction

This first unit of Biology 30 examines the structure and function of the nervous and endocrine systems in detail. You will study how humans interact with their internal and external environments and how these two systems respond to maintain equilibrium and system health. Throughout this exploration, you will be aware of the role of technology in detecting, analyzing, and enhancing the functions of these systems.

In Biology 20, you learned a great deal about equilibrium and maintaining a balance both within the biosphere and within the functioning of the human organism. In this unit, you will develop a greater awareness of the structures and functions of your own nervous and endocrine systems and the conditions necessary to maintain their homeostasis.

This unit has two modules:

The first module is dedicated to the nervous system, which responds to internal and external stimulation. You will explore how the nervous system communicates this information throughout the body.
The second module focuses on the role of the endocrine system and how it works to support homeostasis by releasing hormones into the blood.

Together, these lessons support your understanding of how the two systems work together to maintain equilibrium and system health while the body responds to constantly changing internal and external environments.

Specifically, you will learn to

describe how the nervous and endocrine systems maintain homeostasis
explain how the human body maintains equilibrium between its internal environment and external environment
describe the physiological processes and control systems involved in maintaining homeostasis
analyze the medical technologies available to treat disorders of the nervous and endocrine systems

As you work through the lessons in this unit, you will encounter self-checks and labs to help you practise concepts, assignments to allow you to solve problems and demonstrate your skills, and quizzes to assess your knowledge.
