Explanation:

Peyer's patches are organized lymphoid nodules found in the small intestines, specifically in the ileum.

Peyer's patches contain B lymphocytes in germinal centers and T lymphocytes in surrounding zones, providing a primary and secondary lymphoid organ within the gastrointestinal tract.
