Question

Quizplus · Accepted Answer

When the immune system attacks self antigens, it is referred to as an autoimmune disease. This occurs when the immune system is unable to distinguish between self and non-self antigens, leading to an attack on the body's own tissues. Examples include rheumatoid arthritis and multiple sclerosis.

Option A is incorrect because immediate hypersensitivity allergic reactions occur when the immune system overreacts to harmless substances, such as pollen or food, not when it fails to function.

Option C is incorrect because immune deficiency disorders occur when the immune system fails to function properly, leading to an increased susceptibility to infections and other diseases.

Option D is incorrect because autoimmune diseases are caused by an overreaction of the immune system, not a failure to react.

Option E is incorrect because delayed hypersensitivity allergic reactions occur when the immune system overreacts to certain antigens, such as those found in certain drugs or chemicals, and typically take several hours or even days to occur.
