Life Science: Human Body Systems

Life Science: Human Body Systems

Introduction

Welcome

In this module, you’ll explore how the human body works — from the tiniest cells to the major systems that keep you alive every day.

Learning Goals

By the end of this module, you will be able to:

Identify the major human body systems and their main functions.

Explain how cells, tissues, and organs form systems.

Describe how body systems work together to maintain homeostasis.

Apply what you learn to GED-style science questions.

Why it Matters

Science isn’t just about memorizing facts — it’s about understanding how your own body works. Knowing how body systems function will help you:

Think critically on test questions

Connect science to real-life experiences

Build confidence in your understanding of biology

What to Expect

This course will take you about 10-12 days to complete. You can take as much or as little time as you need. Following this introduction, you will complete a pre-assessment, followed by a series of lessons, activities, and quizzes to help you master the science of the human body. Take notes, complete the practice quizzes, and review key vocabulary often. Most of all, try your best and reach out to your course instructor if you need help!
