Ch 43: Campbell Biology Chapter 43: The Immune System

About This Chapter

The Immune System chapter of this Campbell Biology Companion Course helps students learn the essential lessons associated with the immune system. Each of these simple and fun video lessons is about five minutes long and is sequenced to align with the Immune System textbook chapter.

How It Works:

  • Identify the lessons in the Campbell Biology Immune System chapter with which you need help.
  • Find the corresponding video lessons with this companion course chapter.
  • Watch fun videos that cover the immune system topics you need to learn or review.
  • Complete the quizzes to test your understanding.
  • If you need additional help, rewatch the videos until you've mastered the material or submit a question for one of our instructors.

Students will learn:

  • Components of the innate immune system
  • Components of the acquired immune system
  • Features of the humoral immune response
  • Steps in the cell-mediated immune response
  • Types of adaptive immunity
  • Types of hypersensitivity
  • The definition for an autoimmune disease

Innate Immunity: Inflammation, Neutrophils & Natural Killer Cells

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

The innate immune system builds a defense against dangerous pathogens and other foreign invaders of the body. Explore the innate immune system and discover the functions of various immune cells, like neutrophils, which are the first immune cells to respond to wounds.

Acquired Immunity: T Cells, B Cells and Antibodies

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

People who have acquired immunity against an illness cannot be infected with it again. Discover how T cells, B cells, and antibodies work together to fight illnesses in this lesson.

The Humoral Immune Response: Definition and Features

3. The Humoral Immune Response: Definition and Features

The body's humoral immune response is designed to protect it from bacteria that cause infections. Learn about the definition of the humoral immune response and explore its features, including antigen presenting cells, B cells, and plasma cells. Understand how the humoral immune response helps defend the body from disease by engulfing and breaking down pathogens.

Cell-Mediated Immune Response: Definition, Steps & Features

4. Cell-Mediated Immune Response: Definition, Steps & Features

Cell-mediated immune response involves steps of identification and destruction of harmful bacteria or viruses to prevent further infection. See how T cells operate, noting the different types and functions that they perform in immune response.

What Is Adaptive Immunity? - Definition and Types

5. What Is Adaptive Immunity? - Definition and Types

The adaptive immune system learns to combat specific threats or antigens, allowing the body to adapt and fight new diseases. Learn the definition of adaptive immunity, and then explore the different types of adaptive immunity, including active, passive, naturally acquired, and artificially acquired immunity.

Type I Hypersensitivity: Allergic Reactions

6. Type I Hypersensitivity: Allergic Reactions

A type I hypersensitivity reaction occurs when the immune system produces an overabundance of IgE antibodies to counteract an allergen. Learn more about the pathophysiology of type I hypersensitivity and discover how it relates to anaphylactic shock.

Type II Hypersensitivity: Cytotoxic Hypersensitivity

7. Type II Hypersensitivity: Cytotoxic Hypersensitivity

Type II hypersensitivity is an antibody-mediated immune reaction that can result in impairment or destruction of bodily tissues. Learn about type II and cytotoxic hypersensitivities, how destruction occurs by connections in the body, and how type II hypersensitivity reactions cause disease.

Type III Hypersensitivity: Immune Complex Hypersensitivity

8. Type III Hypersensitivity: Immune Complex Hypersensitivity

Type III hypersensitivity, or immune complex hypersensitivity, is when antibodies form aggregates of antibodies and antigens called immune complexes. Discover type III hypersensitivity reactions and how they can cause vasculitis, arthritis, and glomerulonephritis in this lesson.

Type IV Hypersensitivity: Delayed-Type Hypersensitivity

9. Type IV Hypersensitivity: Delayed-Type Hypersensitivity

Humans can experience significant inflammatory reactions from delayed antigen responses caused by type IV hypersensitivity, also dubbed delayed-type hypersensitivity. Learn about type IV hypersensitivity, why T lymphocytes are dangerous to healthy cells and find examples of reactions and diseases.

Autoimmune Diseases and Hypersensitivity

10. Autoimmune Diseases and Hypersensitivity

Autoimmune diseases occur when the immune system attacks the body's cells or receptors. Explore the friendly fire that creates autoimmune diseases and hypersensitivity reactions, and then discover the different types of autoimmune diseases.
