Third Line of Defence - Unit 3 Biology Immune System Innate immunity: the first line of defense against SARS-CoV-2 Your immune system provides multiple layers of defenses. This line of defense is the immune response. Immune response: MedlinePlus Medical Encyclopedia Third line of defence The third and final line of defence is the immune response. However, if an immune response is activated when there is not a real threat or after the danger passes, the person suffers from allergic reactions and autoimmune disease. It incorporates a specific response for each specific pathogen, resulting in adaptive immunity that is mediated by specialist Lymphocytes (cell mediated immunity) or antibodies (humoral immunity). It recognises invaders such as bacteria, viruses and fungi as well as abnormal cells. The third line of defence (functions that provide independent assurance) is provided by internal audit. The immune system in mammals can be broken down into 2 major subsystems, the innate and the adaptive. takes five to ten days for the body to reach its maximum production of B and T cells - Kill harmful pathogens Specific Immune Response Cont. austincc.edu The immune system can be divided into three basic lines of defense against pathogenic infection:The first line of defense against infection are the surface barriers that prevent the entry of pathogens into the bodyThe second line of defense are the non-specific phagocytes and other internal mechanisms that comprise innate immunityThe third line . The second line of defence takes action when the first line of defence has failed. The innate immune system is the first part of the body to detect invaders such as viruses, bacteria, parasites and toxins, or to sense wounds or trauma. It protects you against all antigens. If a pathogen breaches these barriers, the innate immune system provides an immediate, but non-specific response. They are then transported in the blood to . The second line of defense of the "early-warning" system consists of natural killer cells, phagocytes, eosinophils, dendritic cells, macrophages, inflammation, fever, and antimicrobial substances (Joanne M. Willey, 2014).
