About This Chapter
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.
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.
7. 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.
8. The Lymphatic System: Definition and Fundamental Components
This lesson will cover something known as the lymphatic system. You'll learn about bone marrow, lymph, the thymus, lymph nodes, spleen, and much more as we explore this critical component of your immune system.
9. 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!
10. 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.
11. 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.
12. 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.
13. 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.
14. 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.
