Understanding the Answer
Let's break down why this is correct
Answer
In autoimmune diseases the immune system mistakenly attacks the body’s own tissues, such as the skin, joints, or organs. This misdirected attack is caused by immune cells confusing self‑proteins for foreign invaders, so they release inflammatory chemicals. The inflammation then damages the tissues, causing pain, swelling, or loss of function. For example, in rheumatoid arthritis the immune system targets cartilage in the joints, leading to joint pain and stiffness. This cycle of attack and inflammation is what makes autoimmune diseases chronic and difficult to treat.
Detailed Explanation
The immune system thinks its own cells look like enemies and attacks them. Other options are incorrect because A common mistake is to think the attack is against harmful germs; Antigens are the signals that trigger a response, and they can come from inside or outside the body.
