Goblet and Secretory Cells
Colored transmission electron micrograph of a section through a goblet cell and secretory cells of the duodenum, part of the small intestine.
- Goblet cells (pink & blue) secrete mucus which neutralizes stomach acid.
- Mucigen granules (circular objects, at upper center) combine with water to form the mucus.
- On either side of the goblet cell are the secretory cells whose secretions help in the digestive process.
- The microvilli (green hair- like structures, upper frame) serve to increase the secretory capacity of the secretory cells by increasing their surface area.
