All but one of the following occurs during the inflammatory response. Select the example below that does NOT describe the process of inflammation.

A. Participate in the specific immune response formation:Cytotoxic T cells are part of the adaptive immune system and require antigen-specific activation. NK cells, however, are part of innate immunity and act non-specifically, so this is not a similarity between them.

B. Secrete interferons:While both cell types can influence interferon activity indirectly, their main cytotoxic function does not rely on interferon secretion. This is not the defining feature that makes them similar.

C. Participate in nonspecific resistance:Cytotoxic T cells act in a specific, antigen-dependent manner, unlike NK cells, which function nonspecifically. Therefore, nonspecific resistance is only a feature of NK cells, not both.

D. Secrete granzymes and perforin:Both cytotoxic T cells and natural killer cells kill target cells by releasing granzymes and perforin. Perforin forms pores in the target cell membrane, allowing granzymes to enter and trigger apoptosis, making this their shared cytotoxic mechanism.

A. Lymph nodes:Lymph nodes filter lymph and provide immune surveillance, but they do not directly absorb or transport dietary fats from the small intestine to the bloodstream.

B. Tonsils:Tonsils are lymphoid tissues located in the pharynx that trap pathogens entering through the mouth or nose. They play no role in fat absorption or transport.

C. Peyer’s patches:Peyer’s patches are lymphoid follicles in the small intestine that monitor intestinal bacteria and facilitate immune responses. They are not involved in the absorption of dietary fats.

D. Lacteals:Lacteals are specialized lymphatic capillaries located in the villi of the small intestine. They absorb dietary fats in the form of chylomicrons and transport them via lymph to the bloodstream, bypassing the hepatic portal system.
