Question: 175: Given below are two statements:
Statement I:
Autoimmune disorder is a condition where body defense mechanism recognizes its own cells as foreign bodies.
Statement II:
Rheumatoid arthritis is a condition where body does not attack self cells.
In the light of the above statements, choose the most appropriate answer from the options given below:
(1) Statement I is correct but Statement II is incorrect
(2) Statement I is incorrect but Statement II is correct
(3) Both Statement I and Statement II are correct
(4) Both Statement I and Statement II are incorrect
Answer: Option (1)
Explanation:
Autoimmune disorders occur when the immune system fails to recognize self cells
and mistakenly treats them as foreign.
This leads to an immune response against the body’s own tissues.
Therefore, Statement I correctly defines an autoimmune disorder.
Rheumatoid arthritis is an autoimmune disease in which the immune system attacks the synovial joints.
Hence, the body does attack its own cells in rheumatoid arthritis.
Since Statement II incorrectly states that the body does not attack self cells, it is incorrect.
Thus, Statement I is correct but Statement II is incorrect.
