Study Notes
Small Intestine Structure
- The small intestine is composed of multiple tissue layers.
- The inner lining is mucosa, an epithelial tissue.
- Beneath the mucosa is the submucosa, a layer of connective tissue.
- Circular muscle fibers are present in the small intestine.
- Longitudinal muscle fibers are also present.
- The outer layer of the small intestine is the serosa, which is connective tissue.
- Villi (finger-like projections) are epithelial tissue found within the mucosa, increasing surface area for absorption.
