RRD‑3 – Mechanisms of Defense: Inflammation and Immune Function and Disorders Practice Test

Inadequate immune responses can lead to autoimmune diseases because when the immune system is not functioning properly, it can develop a misdirected or excessive response to self-antigens, mistakenly attacking the body’s own tissues. This results from an inability to adequately differentiate between foreign pathogens and the body's own cells, which can trigger chronic inflammation and tissue damage typical of autoimmune disorders.

In contrast, the other options do not accurately reflect the consequences of inadequate immune responses. Increased inflammation typically results from overactive immune responses rather than insufficient ones. Enhanced pathogen elimination would be characteristic of an effective immune response, while reduced risk of infection occurs when the immune system is functioning optimally, rather than inadequately.
