The Basics of the Immune System: How Your Body Defends and Balances Itself

In this episode of This Could Save Your Life podcast, Dr Catherine Bourke is joined by Dr Jack Bourke, clinical immunologist and immunopathologist, to discuss the fundamentals of the immune system.Dr Jack explains the core functions of the immune system, including defending against pathogens such as viruses, bacteria, parasites, and fungi, as well as identifying and removing abnormal or cancerous cells. The distinction between the innate (rapid, broad-acting, present from birth) and adaptive (specific, develops over time, retains memory) components of immunity is outlined.Describing the diffuse nature of the immune system across the body, incorporating white blood cells, bone marrow, thymus, lymph nodes, spleen, tonsils, adenoids, skin, and mucosal surfaces. The implications of removing structures like tonsils, adenoids, and especially the spleen are discussed, noting that only loss of the spleen is associated with significant immune deficiency and additional infection risk.Dr Jack addresses the misconception that the immune system is only active during illness. Reviewing the role of lifestyle factors on immune health, alongside the lack of evidence for most over-the-counter “immune-boosting” products outside correction of proven deficiencies.Key evidence-based interventions to support immune health include vaccination, healthy diet, physical activity, adequate sleep, and chronic disease management.This Could Save Your Life Podcast is under The Good GP podcast, a proud member of the Talking HealthTech Podcast Network - the premier audio destination for cutting-edge insights and thought leadership in healthcare delivery, innovation, digital health, healthcare ICT, and commercialisation.
