Verified step by step guidance

Understand the function of Peyer's patches: Peyer's patches are lymphoid tissues that play a role in immune surveillance and defense against pathogens in the digestive system.
Identify the location of Peyer's patches: They are specifically found in the mucosa and submucosa of the ileum, which is the last part of the small intestine.
Eliminate incorrect options: Liver lobules are part of the liver's structure, cortex of the kidney is related to kidney filtration, and alveoli of the lungs are involved in gas exchange. None of these are related to Peyer's patches.
Focus on the ileum of the small intestine: The ileum is the correct anatomical location where Peyer's patches are concentrated, aiding in immune function within the gastrointestinal tract.
Conclude the reasoning: Based on their function and location, Peyer's patches are found in the ileum of the small intestine, not in the liver, kidney, or lungs.
