Which of the following best describes the role of antigen transport in initiating an adaptive immune response: A) Preventing chronic infections by enhancing tolerance. B) Facilitating innate recognition of pathogens by physical barriers. C) Directly neutralizing pathogens at the site of infection. D) Delivering processed pathogen fragments to immune cells in lymphoid organs.
Understand the Problem
The question is asking for the best description of how antigen transport contributes to starting an adaptive immune response. This involves understanding the mechanisms of the immune system, especially how antigens are processed and delivered to initiate a response from immune cells.
Answer
D) Delivering processed pathogen fragments to immune cells in lymphoid organs.
The final answer is D) Delivering processed pathogen fragments to immune cells in lymphoid organs.
Answer for screen readers
The final answer is D) Delivering processed pathogen fragments to immune cells in lymphoid organs.
More Information
Antigen transport plays a crucial role in the adaptive immune response by delivering processed pathogen fragments (antigens) to immune cells, such as T cells, in lymphoid organs. This process is essential for the activation and proliferation of specific immune responses against pathogens.
Tips
A common mistake is to confuse the roles of innate and adaptive immunity. Innate immunity involves immediate responses, whereas adaptive immunity is highly specific and involves the recognition of processed antigens.
