  2. Intestinal villus - Wikipedia

    en.wikipedia.org/wiki/Intestinal_villus

    Intestinal villi (sg.: villus) are small, finger-like projections that extend into the lumen of the small intestine. Each villus is approximately 0.5–1.6 mm in length (in humans), and has many microvilli projecting from the enterocytes of its epithelium which collectively form the striated or brush border .

  3. Jejunum - Wikipedia

    en.wikipedia.org/wiki/Jejunum

    The villi of the jejunum look like long, finger-like projections, and are a histologically identifiable structure. While the length of the entire intestinal tract contains lymphoid tissue , only the ileum has abundant Peyer's patches , which are unencapsulated lymphoid nodules that contain large numbers of lymphocytes and immune cells, like ...

  4. Small intestine - Wikipedia

    The small intestine supports the body's immune system. [20] The presence of gut flora appears to contribute positively to the host's immune system. Peyer's patches, located within the ileum of the small intestine, are an important part of the digestive tract's local immune system. They are part of the lymphatic system, and provide a site for ...

  9. Intestinal epithelium - Wikipedia

    Drawing showing the relationship between villi and microvilli of the small intestine. The luminal surface of the enterocytes have microvilli (1 micrometer long) while the cell layer itself is folded to form villi (0.5-1.6 millimeters long) and crypts. Both serve to increase the total absorption surface of the intestine.
