The Complement System: Definition and Function

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.

The Lymphatic System: Definition and Fundamental Components

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.

The Humoral Immune Response: Definition and Features

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.

Antibodies: Their Important Structure

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.

Antibodies: Their Function In the Immune System

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.

The Five Classes of Antibodies

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.

Cell-Mediated Immune Response: Definition, Steps & Features

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.

Granulocytes: Types and Functions

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.

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.
