Structure & Function of the Immune System - Chapter Summary
Explore this mobile-friendly science chapter to study the structure and function of the human immune system. Inside, you'll find a series of bite-sized lessons that break down topics like humoral immune response, antibody classes, granulocytes, cell types and macrophages. The chapter is available to study at any time of day or night, and it comes with lesson-specific quizzes and a comprehensive exam. If you have any questions about these concepts, simply reach out to our expert science instructors online. When you're finished with the chapter, you'll be able to:
- Understand the functions of the complement system and the alternative complement pathway
- Identify the fundamental components of the lymphatic system
- Recognize humoral immune response features
- Evaluate the structure and functions of antibodies
- Discuss the five antibody classes
- Outline the steps of cell-mediated immune response
- Compare different types of granulocytes
- Understand the roles of killer cells, macrophages and other innate immune system cells
- Assess the functions of T cell and B cells
1. 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.
2. 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.
3. 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.
4. 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.
5. 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.
6. 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.
7. Cell-Mediated Immune Response: Definition, Steps & Features
Our immune systems are pretty good, but sometimes pathogens can sneak in and infect living cells. Luckily, we've got a back up system. Let's explore cell-mediated response and see how this protects our bodies from infections that may otherwise go untreated.
8. 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.
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.
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!
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.
