Understanding Inflammation
The immune system is a complex network of cells, tissues, and proteins that work together to defend the body against harmful invaders such as viruses, bacteria, and other pathogens. This course explores how the body recognizes foreign threats, triggers an immune response, and utilizes inflammation to protect and heal.

Learning Outcomes
What you'll learn
- Understand how immune cells and proteins protect the body from harmful pathogens in UK healthcare settings.
- Learn how the body detects viruses and bacteria and starts an immune response to infection.
- Understand how inflammation develops and how neutrophils move to sites of infection or tissue injury.
- Explore how antigen presenting cells connect innate and adaptive immunity during the immune response.
- Learn how B cells develop and produce antibodies that help the body fight harmful pathogens.
- Understand how antibodies help clear infections and support safe patient care.
- Apply knowledge of immunity and inflammation to infection prevention and control in UK healthcare settings.

Frequently Asked Questions
The immune system is the body’s defense network of cells, tissues, and organs that protects against infections and harmful pathogens like bacteria, viruses, fungi, and parasites.
Innate immunity provides immediate, non-specific defense, while adaptive immunity develops a targeted response using T-cells, B-cells, and antibodies for long-term protection.
Inflammation increases blood flow and immune cell movement to infected or injured areas, helping eliminate pathogens and initiate tissue repair.
Antigen-presenting cells link innate and adaptive immunity by presenting pathogen fragments to T-cells, triggering a specific immune response and antibody production.
