Question

Rheumatoid arthritis is an autoimmune disease.

Answer 1

Autoimmune disease:

1. It is a disease when our body's immune system fails to differentiate normal body cells and foreign material (self cells with non-self cells).
2. As a result, the immune system mistakenly attacks its own body cells or tissue causing their damage.

Rheumatoid Arthritis:

1. It is a condition of inflammation in joints.
2. This condition develops when the body's immune system mistakenly attacks its own cells that line the joints.
3. It results in joint pain, swelling, stiffness of joints, etc.
4. As, in rheumatoid arthritis, the body's immune cells start attacking its own cells assuming them as foreign particles, hence, it can be considered an autoimmune disease.
