The first image (on the right) is the human appendix. The appendix is a worm-shaped tube attached to the large intestine in the human body. Like the colon, it is characterized as having straight crypts with no villi. But unlike the colon, the tissue illustrated contains an abundant number of lymphoid tissues including well-organized lymph nodes. The appendix is an organ with very little significance and is often removed indiscriminately to avoid complications due to infection. The inner lining of the tissue, which faces the lumen, is covered by a glandular epithelium containing intestinal mucus glands that stretch into the deeper layers of the mucosa. The glands are lined with simple columnar epithelium and a high number of gastrointestinal endocrine (argentaffin cells) and mucin-producing goblet cells.
