The gastrointestinal wall is composed of four layers or tunics:
- Mucosa
- Submucosa
- Muscularis mucosa
- Serosa
The innermost tunic of the wall is known as the mucosa or mucous membrane layer. The digestive tract's lumen is lined with it. The mucosa comprises epithelium, a layer of lamina propria, a loose layer of connective tissue, and the muscularis mucosa, a thin layer of smooth muscle.
The mucosa is surrounded by a substantial layer of loose connective tissue known as the submucosa. Blood arteries, lymphatic vessels, and neurons are also present in this stratum. The adventitia is a connective tissue that makes up the digestive tract's outermost layer above the diaphragm. It is referred to as serosa below the diaphragm.
