Study Notes
Introduction to Immunology
- Immunology is the branch of biology concerned with the body's defense reactions.
- Immunity refers to protection against infection.
The Immune System
- The immune system is the collection of organs, tissues, cells, and molecules that defend the body against infectious agents.
- It is responsible for the immune response, which is the coordinated reaction against infections and other foreign substances or antigens.
Organs of the Immune System
- Lymphoid organs are responsible for the development and differentiation of immune cells.
- Primary Lymphoid organs are responsible for the development and differentiation of immune cells.
Learning Objectives
- Define basic immunological terms.
- Describe the immunological components of the immune system.
- Outline the functions of different immunological components of the immune system.
- Discuss how immune cells are identified based on CD markers.
- List and explain the characteristics of the immune system.
- Explain how immune cells communicate.
- List the consequences of disturbance of the immune system.
Test your knowledge of basic immunological terms, the components and functions of the immune system, identification of immune cells, characteristics of the immune system, communication among immune cells, and consequences of disturbances in the immune system.
