पर्याय

• immunologic tolerance

• autoimmunity

• severe combined immunodeficiency disease

• hypersensitivity

Answer 1

The ability of the body’s immune system to recognize its own tissues is known as immunologic tolerance.

Explanation:

Immunologic tolerance refers to the immune system’s ability to recognize and not attack the body’s own tissues, preventing an autoimmune response. It ensures that immune cells distinguish ‘self’ from ‘non-self’ substances. In contrast, autoimmunity is the loss of this tolerance, leading to immune attacks on self-tissues. Severe combined immunodeficiency disease and hypersensitivity refer to other immune dysfunctions unrelated to self-recognition.
