Lymphoid nodule aggregates: Appendix
The appendix is a narrow, blind-ended tube attached to the cecum, the initial region of the large intestine. Though considered a portion of the tubular digestive tract, the lamina propria of the appendix is heavily infiltrated with lymphoid tissue forming numerous secondary nodules. As such, the appendix is an important component of the mucosal immune system. 40x
