The Mucosal Tissues of the Body Have Their Own Unique

question 3

Multiple Choice

The mucosal tissues of the body have their own unique set of immune structures that function as sites for initiating adaptive immune responses. The necessity for mucosa-associated lymphoid tissues to have unique cell types (M cells) and structures is because:

• A) The mucous layer lining mucosal surfaces makes it difficult for normal antigen-presenting cells to function.
• B) The epithelial surfaces that line the gut, lungs, and nasal passages prevent antigen-presenting cells from accessing microbes and microbial products.
• C) The epithelial cells found in mucosal tissues are distinct from those that provide barrier functions to the skin.
• D) Mucosal sites, where most pathogens access the body, are exposed to vast numbers of diverse microbes.
• E) Mucosal tissues lack innate sensor cells that can respond to PAMPs and provide short-term innate immune protection.
