In no time, you should be ready to:
- List major anatomical barriers to infection of the immune system
- Share the meaning and processes of antigens
- Identify and describe the steps of the inflammatory response
- Describe the lymphatic system, immune response and cell-mediated immune response
- Detail the process of phagocytosis
- Explain the functions of antibodies and lymphocytes
- Discuss vaccination and immunotherapy in disease prevention and treatment
- Provide details about how the immune system responds to transfusions and transplants
Review the lessons in this chapter in your sequence of choice, and feel free to revisit them as often as needed during your studying process. If you hit a snag and need additional information, don't hesitate to send your questions to our experts. With each lesson is a short quiz you can take to find out how much you understand about the immune response concepts covered. A practice exam is also available to reinforce your comprehension of this chapter.
1. 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.
2. Antigen: Meaning & Explanation
Antigens are invaders that sneak into our bodies and can possibly cause us harm; however, they trigger our immune system, which fights them off. This lesson explains antigens and some of the processes that go along with them.
3. The Inflammatory Response: Definition & Steps
The inflammatory response is a part of your innate immune system that responds to infection and injury. In this video, you'll learn about the process of inflammation and what happens when it becomes chronic.
4. The Lymphatic System & Immune Response
How does your body stay healthy when there are so many germs attacking it? Learn more about the lymphatic system that helps circulate immune cells that protect you from disease.
5. Phagocytosis: Definition, Process & Types
Phagocytosis is the process by which a cell engulfs material either to destroy it, to feed on it, or to get information from it. Learn how important this process is to your own immune system.
6. 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.
7. What Are Antibodies? - Definition, Function & Types
Antibodies play a key role in the immune system. They begin the process of getting rid of the invaders that may cause harm or infection. This lesson covers how antibodies work and the different kinds of antibodies.
8. Lymphocytes: Definition, Functions & Types
Our bodies contain numerous types of cells. In this lesson, you will learn about a type of cell known as a lymphocyte. You will also gain an understanding of the types of lymphocytes, as well as their functions in the body.
9. Vaccination and Immunotherapy
This lesson will discuss the basics of how diseases can be prevented or treated using our own immune system's components. We'll talk about vaccination and immunotherapy as well as some specific examples, such as the BCG vaccine, monoclonal antibodies, and more.
10. Transfusion and Transplant Reactions
A transfusion reaction occurs when incompatible blood is given to a recipient. A transplant rejection occurs when an incompatible organ or tissue is given to a recipient. Learn about these reactions and tests that are done to lessen their effects.
