RRD‑3 – Mechanisms Of Defense: Inflammation And Immune Function And Disorders Practice Test

Multiple sclerosis is considered a tissue-specific autoimmune disease because it primarily targets the central nervous system, specifically the myelin sheath that covers nerve fibers. In this condition, the immune system mistakenly attacks and damages healthy tissues, resulting in neurological symptoms due to the disruption of nerve signal transmission. This localized attack on a specific type of tissue, the nervous system, distinguishes it from more generalized inflammatory responses seen in other conditions. Asthma, while it involves an immune response, is characterized by chronic inflammation of the airways and is not classified as tissue-specific since it affects multiple systems and is more about the environment triggering overreaction rather than an autoimmune process. Allergic rhinitis is primarily an allergic reaction and involves the immune response to environmental allergens rather than targeting specific tissues. Chronic inflammation is a continual inflammatory response and can occur across various tissues and systems, rather than being localized to a specific tissue type.
