Peyer's Patches
Specialized lymphoid nodules located in the wall of the small intestine, playing a key role in immune responses against ingested substances.
Lymph Nodules
Lymph nodules are small, localized clusters of dense tissue found within the lymph system, important for immune responses and filtration of bodily fluids.
Small Intestinal Wall
