GLANDULAR EPITHELIA

SMALL BOWEL:

In the small intestine, both cells and structures are modified for absorption rather than secretion. Although a few mucin-containing goblet cells are seen, most are smaller cells rendered a deep red-pink by their numerous mitochondria and other pumping machinery require for membrane transport. The overall architecture is dominated by finger-like villi which project into the lumen. In a well-oriented specimen, they are parallel and of near equal length. The submucosa and muscularis propria are similar to those of the colon.
