It discusses the two main types of immunity, innate and adaptive, and how they work together to protect the body from harmful pathogens and diseases. The page describes the key components of the immune system, including various specialized cells such as white blood cells, lymphocytes, and antibodies. It also explains the role of lymphoid organs, such as the thymus, spleen, and lymph nodes, in immune responses. Furthermore, the article delves into the process of immune recognition, highlighting how the immune system distinguishes between self and non-self molecules, and how it mounts a response when encountering foreign substances. It discusses the importance of antigen presentation, the role of major histocompatibility complex molecules, and the activation of T-cells and B-cells. The page expands on various aspects of immune responses, including inflammation, phagocytosis, and the production of antibodies. It explores the concept of immunological memory, whereby the immune system can remember and respond faster to previously encountered pathogens, leading to a stronger and faster immune response upon re-exposure. The article also covers the topics of immunodeficiency, hypersensitivity reactions, and autoimmune diseases, providing an overview of how immune dysregulation can lead to various disorders and conditions. Overall, the Wikipedia page on Immunity (medical) offers a detailed exploration of the role and functioning of the immune system in medical contexts. It serves as a valuable resource for anyone seeking to understand the complex mechanisms of immune responses and their implications for human health.
