Ch 20: Microbiology: The Immune System

About This Chapter

Our professional instructors will help you understand the immune system through engaging and informative video lessons. This chapter will detail T-cells, antibodies, and more.

Microbiology: The Immune System - Chapter Summary

In this chapter we'll be taking a look at the immune system as it relates to microbiology. You'll learn all about anatomical barriers, adaptive immunity, the lymphatic system and many other topics. Our expert instructors will also help you understand topics like:

  • How T-Cells are created and what their function is
  • How antibodies are structured and why its important
  • Antibody classification
  • Common causes and symptoms of inflammation
  • Features of the humoral immune response system
  • Different types and the function of granulocytes

With a combination of expert instructors leading professional quality video lessons, we'll make the immune system an easy to understand concept. Each video comes with accurate transcripts and convenient video tags making it easy for you to navigate through the lessons. Our chapter video lessons are tailored to meet your needs as you prepare for your examination and end of lesson self-assessment quizzes will help you keep track of your progress and help you pinpoint what topics you're still struggling with.

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

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

The immune system is an individual's private security system, protecting oneself from illness and disease. Learn about the immune system and two of its several defenses, the innate and adaptive immune systems, and explore how they work together and are affected by immune tolerance.

The Anatomical Barriers of the Immune System

2. The Anatomical Barriers of the Immune System

There are two main parts of the immune system: the innate immune system, made up of anatomical barriers, and the adaptive immune system. Discover the anatomical barriers of the immune system, how the skin and gut flora kill off bacteria, and the functions of the eyes and respiratory tract enzymes.

What Is Inflammation? - Definition, Causes & Symptoms

3. What Is Inflammation? - Definition, Causes & Symptoms

When the body is attacked by something it deems harmful, a response called inflammation often occurs. Learn the definition of inflammation, its causes, symptoms, and its relationship to the immune system, and examine its components and influences in the body, the relationship between histamine and cytokines, and the short- and long-term consequences that can result from inflammation.

Granulocytes: Types and Functions

4. Granulocytes: Types and Functions

Granulocytes are white blood cells with granules in their cytoplasm. Discover the functions of granulocytes and the types of granulocytes: neutrophils, eosinophils, and basophils in this lesson.

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

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

The innate immune system contains cells called macrophages that eat other cells in order to destroy them in a process called phagocytosis. Explore the roles of macrophages, monocytes, phagocytes, mast cells, and other natural killer cells that the immune system uses in its ongoing battle against infection.

The Complement System: Definition and Function

6. The Complement System: Definition and Function

The complement system is part of the body's immune system that helps destroy microorganisms that cause infections. Learn about the complement system, including its definition and function. Explore how the complement system acts as a sprinkling for defense, and review opsonization, chemotaxis, and membrane attack complex.

What Is Adaptive Immunity? - Definition and Types

7. 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.

The Lymphatic System: Definition and Fundamental Components

8. The Lymphatic System: Definition and Fundamental Components

The lymphatic system is comprised of organs, vessels, tissues, and ducts that create and transport lymph throughout the body. Learn about the definition and fundamental components of the lymphatic system.

What are T Cells: Creation and Function

9. What are T Cells: Creation and Function

A T cell, also known as a T lymphocyte, is a white blood cell with a major role in the body's immune system. Learn about the creation and function of T cells, the roles of T helper cells, and the production and maturation of T cells.

What Are B Cells? - Function and Types

10. What Are B Cells? - Function and Types

B-cells are vital in the production of antibodies. Explore the function of B-cells and the types of B-cells such as naive B-cells, active B-cells, plasma cells, and memory cells. Plus, discover the rare disease X-linked agammaglobulinemia in this lesson.

The Humoral Immune Response: Definition and Features

11. 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.

Antibodies: Their Important Structure

12. Antibodies: Their Important Structure

Antibodies, also called immunoglobulins, are structures that attack bacteria, viruses, and other foreign substances in the body. Learn about antibody structure, their chains and domains, and the importance of the paratope and epitope.

Antibodies: Their Function In the Immune System

13. Antibodies: Their Function In the Immune System

Antibodies help your body fight off disease-causing bacteria, viruses, and other foreign substances in the blood. Learn how antibodies function in the immune system and how they use opsonization, agglutination, and neutralization to stop threats to the body.

The Five Classes of Antibodies

14. The Five Classes of Antibodies

Antibodies help your body fight off disease-causing bacteria, viruses, and other foreign substances in the body. Learn the five classes of unique isotopes, including Immunoglobulins G, M, A, D, and E, and explore how they function.
