Students will review:

In this chapter, you'll learn the answer to questions including:

  • How do innate, acquired and adaptive immunity differ?
  • What are some causes of inflammation?
  • What are the structures and functions of antibodies?
  • What are the five classes of antibodies?
  • What kind of cells make up the innate immune system?
  • How do T and B cells function?

What Is the Immune System? - Our Body's Defense Against Pathogens

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.

Innate Immunity: Inflammation, Neutrophils & Natural Killer Cells

2. Innate Immunity: Inflammation, Neutrophils & Natural Killer Cells

You might already know how your body handles known infectious agents but how about unknown? Watch this video to explore your innate immune system - your body's defense against new bacteria and viruses.

What Is Inflammation? - Definition, Causes & Symptoms

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.

Acquired Immunity: T Cells, B Cells and Antibodies

4. Acquired Immunity: T Cells, B Cells and Antibodies

Have you ever wondered why some people don't ever seem to get sick? These people likely have an acquired immunity. Learn more about the immune system and how exposure to an illness one time can help your body to prevent that illness from ever occurring again.

What Is Adaptive Immunity? - Definition and Types

5. What Is Adaptive Immunity? - Definition and Types

This lesson will help you distinguish between several different types of immunity. This includes passive immunity, active immunity, naturally acquired immunity and artificially acquired immunity.

Antibodies: Their Important Structure

6. Antibodies: Their Important Structure

This lesson will cover the basic but important structural components and sites of an antibody as well as their function. This includes heavy chains, light chains, variable domains, constant domains, paratopes, and epitopes.

Antibodies: Their Function In the Immune System

7. Antibodies: Their Function In the Immune System

This lesson will delve into the three main ways by which antibodies function. We're going to discuss opsonization, agglutination and neutralization. We'll also learn what the Fc region is and why it's important.

The Five Classes of Antibodies

8. The Five Classes of Antibodies

This lesson will cover the five different classes, or isotypes, of antibodies. We will cover IgA, IgE, IgG, IgM, and IgD, as well as their basic structure and function.

Macrophages, Killer Cells & Other Cells of the Innate Immune System

9. 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.

What are T Cells: Creation and Function

10. What are T Cells: Creation and Function

This lesson will teach about the birth, maturation, and importance of T cells. You'll learn about T lymphocytes, cytotoxic T cells, helper T cells, memory T cells, and more!

What Are B Cells? - Function and Types

11. What Are B Cells? - Function and Types

This lesson will focus in on the generalities of B-cells, such as their place of generation, maturation, and training, as well as some specific types of B-cells, such as plasma cells and memory cells.

The Anatomical Barriers of the Immune System

12. 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.

The Humoral Immune Response: Definition and Features

13. The Humoral Immune Response: Definition and Features

This lesson will describe what humoral immunity is, how it is activated, what is produced, and why. Find out as we explore antigen presenting cells, MHC, T cells, B cells, plasma cells, and antibodies.

The Complement System: Definition and Function

14. 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.

Granulocytes: Types and Functions

15. 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.

Immune System: Function & Responses

16. Immune System: Function & Responses

The immune system is the body's defense against invaders that could do it harm. This lesson covers the different parts and their functions in protecting the body against infections.

Agglutinins & Agglutinogens in the Immune System

17. Agglutinins & Agglutinogens in the Immune System

In this lesson, we'll define agglutinins and agglutinogens and discuss their role in agglutination. We'll also discuss how doctors can use agglutination reactions to prevent rejection of organ transplants and blood transfusions.
