Mucosa layer
Explanation:
The mucosa is the innermost layer, and functions in absorption and secretion
- It is composed of epithelium cells and a thin connective tissue
- The mucosa contains specialized goblet cells that secrete sticky mucus throughout the GI(gastrointestinal)tract
- The mucosa is made up of three layers:epithelium,lamina propria and muscularis mucosae
- The epithelium is the innermost layer and it is responsible for most digestive, absorptive, and secretory processes
- The lamina propria is a layer of connective tissue that is unusually cellular compared to most connective tissue
- The muscularis mucosae is a thin layer of smooth muscle
