Final answer:
In autoimmune diseases like Grave's Disease, Type I diabetes, Multiple sclerosis, and Hemolytic anemia, the immune system attacks thyroid follicular cells, pancreatic beta cells, oligodendrocytes, and red blood cells, respectively.
Step-by-step explanation:
Autoimmune diseases occur when the immune system mistakenly attacks the body's own cells. Here are the specific cells targeted in each listed disease:
Grave's Disease: The immune system attacks the thyroid follicular cells.
Type I diabetes: The immune system attacks pancreatic beta cells that produce insulin.
Multiple sclerosis: The immune system attacks oligodendrocytes, which are the cells that produce myelin in the central nervous system.
Hemolytic anemia: The immune system attacks red blood cells.
All of these conditions result from the immune system failing to recognise these cells as part of the body, leading to chronic inflammation and a variety of symptoms.
