About This Chapter
The Immune System - Chapter Summary and Learning Objectives
Learn how the innate immune system protects our bodies from disease-causing agents with this chapter's engaging video lessons. Multiple-choice quizzes are also included to help you sort out the functions of the immune system's anatomical barriers, white blood cells and proteins. This chapter's lessons are designed to teach you about the following:
- Immune system components
- Causes of inflammation
- Immune system cell functions
- Processes in the complement system
|What Is the Immune System? - Our Body's Defense Against Pathogens||Learn how innate and adaptive immune systems protect the body from pathogens.|
|The Anatomical Barriers of the Immune System||Discover which components of the skin, gastrointestinal tract and respiratory system can fight off pathogens.|
|What Is Inflammation? - Definition, Causes & Symptoms||Identify the symptoms and causes of inflammation.|
|Granulocytes: Types and Functions||Explore the functions of granulocytes, including neutrophils, eosinophils and basophils.|
|Macrophages, Killer Cells & Other Cells of the Innate Immune System||Outline the roles of macrophages, mast cells and NK cells in the immune system.|
|The Complement System: Definition and Function||Examine the various processes and proteins making up the complement system.|
1. What Is the Immune System? - Our Body's Defense Against Pathogens
In this lesson, you will be introduced to the immune system. You'll learn about the innate and adaptive immune system, Edward Jenner, haptens and immune tolerance.
2. The Anatomical Barriers of the Immune System
This lesson will cover the major anatomical barriers to infection of the innate immune system. We'll explore skin flora, gut flora, gastric acid, lysozymes, and the mucociliary apparatus.
3. What Is Inflammation? - Definition, Causes & Symptoms
This lesson will cover the process of inflammation and what your body might do after a bee sting. We'll find out the five cardinal signs of inflammation as well as anaphylactic shock, histamine and cytokines in the process.
4. Granulocytes: Types and Functions
In this lesson, you will learn what a leukocyte, granulocyte, neutrophil, eosinophil, and basophil are. You'll also learn about the importance of phagocytosis and chemotaxis.
5. Macrophages, Killer Cells & Other Cells of the Innate Immune System
This lesson will teach you about certain white blood cells of the innate immune system. Namely, we'll learn about phagocytes, monocytes, macrophages, mast cells, and NK cells.
6. The Complement System: Definition and Function
This lesson will cover something known as the complement system. We'll delve into the key functions of this system, including opsonization, chemotaxis, and the formation of membrane attack complexes.
