Which of the following best describes the primary function of a Peyer's patch in eukaryotic organisms?
A
Synthesis of bile for fat emulsification
B
Production of digestive enzymes for nutrient absorption
C
Initiation of immune responses to antigens in the small intestine
D
Regulation of water reabsorption in the colon
Verified step by step guidance1
Understand the context: Peyer's patches are specialized lymphoid tissues found in the small intestine of eukaryotic organisms. Their primary role is related to the immune system, not digestion or water regulation.
Eliminate incorrect options: The synthesis of bile for fat emulsification occurs in the liver, not in Peyer's patches. Similarly, the production of digestive enzymes is a function of the pancreas and intestinal cells, not Peyer's patches.
Focus on the immune function: Peyer's patches are part of the gut-associated lymphoid tissue (GALT). They monitor intestinal bacteria and pathogens and play a role in initiating immune responses.
Clarify the correct answer: Peyer's patches contain immune cells such as B cells, T cells, and macrophages, which help detect and respond to antigens (foreign substances) in the small intestine.
Conclude: The best description of the primary function of Peyer's patches is 'Initiation of immune responses to antigens in the small intestine.' This aligns with their role in maintaining intestinal immune surveillance.
