Explanation
Hashimoto's thyroiditis can cause your thyroid to not make enough thyroid hormone. It is an autoimmune disease. It occurs when your body makes antibodies that attack the cells in your thyroid.

3.

The immune system's failure to distinguish between self and non-self cells leads to:
- A.
  
  Allergy
- B.
  
  Autoimmunity
- C.
  
  Immunodeficiency
- D.
  
  Cancer
Correct Answer
B. Autoimmunity

Explanation
Autoimmunity is caused by the breakdown in self and nonself discrimination.

Rate this question:
4.

In multiple sclerosis, the immune system attacks:
- A.
  
  The thyroid gland.
- B.
  
  The joints.
- C.
  
  The central nervous system.
- D.
  
  The liver.
Correct Answer
C. The central nervous system.

Explanation

  White blood cells.
- C.
  
  Platelets.
- D.
  
  Antibodies.
Correct Answer

  Soy products.
Correct Answer
B. Wheat gluten.

Explanation
Celiac disease, sometimes called celiac sprue or gluten-sensitive enteropathy, is an immune reaction to eating gluten, a protein found in wheat, barley and rye. If you have celiac disease, eating gluten triggers an immune response in your small intestine.

Rate this question:
7.

Which autoimmune disease primarily affects the small intestine and interferes with nutrient absorption?
- A.
  
  Crohn's disease.
- B.
  
  Lupus.
- C.
  
  Sjögren's syndrome.
- D.
  
  Celiac disease.
Correct Answer
D. Celiac disease.

Explanation
Coeliac disease (CD) is an enteropathy, characterized by villous atrophy, which occurs in genetically susceptible individuals. It affects mainly the proximal small intestine, and is caused by an intolerance to cereal storage proteins found in wheat, barley and rye.

Rate this question:
8.

Which autoimmune disease primarily affects the body's connective tissues, causing symptoms such as joint pain, skin rashes, and fatigue?
- A.
  
  Hashimoto's thyroiditis
- B.
  
  Crohn's disease
- C.
  
  Systemic lupus erythematosus (SLE)
