In a series of immune system experiments, the thymus glands were removed from baby mice. Which of the following would you predict as a likely result?
A
The mice suffered from numerous allergies.
B
The mice never developed cancerous tumors.
C
The mice suffered from autoimmune diseases.
D
The mice were unable to produce an inflammatory response.
E
The mice readily accepted tissue transplants.
Verified step by step guidance1
Understand the role of the thymus gland: The thymus is crucial for the development of T-cells, which are essential for the adaptive immune system. T-cells help the body recognize and attack foreign substances.
Consider the impact of removing the thymus: Without the thymus, the development of T-cells is impaired, leading to a compromised immune system.
Evaluate the options: Analyze each option based on the role of T-cells. Allergies, autoimmune diseases, and inflammatory responses involve immune system activity, which requires functional T-cells.
Focus on tissue transplant acceptance: Without T-cells, the immune system is less likely to reject foreign tissues, making tissue transplants more readily accepted.
Conclude the prediction: The removal of the thymus leads to a lack of T-cell development, resulting in the mice's immune system being unable to reject transplanted tissues, thus they readily accept tissue transplants.
